Incidentally, having enjoyed your comments on the episode, I'd like to point you to some of my own BSG Season 4 observations (and just-barely-in-time finale speculation):

I think Head Six represents a great deal more than simply an expression of unconscious feelings within Baltar, which is what he first theorizes she is, in the very first episode. Also, what she actually is, and represents, as Ron D Moore has already said, is a messenger from God, which presumably also applies to Head Baltar who speaks to Caprica Six.
I agree with the comments made about Helo and Tyrol having a bond through their love of Boomer / Athena. In the beginning, it was Athena who pretended to be Boomer in her seduction of Helo. This is then more recently reversed, with Boomer pretending to be Athena, and having sex with Helo, as Boomer watches helplessly, before kidnapping Hera. What Tyrol says to Helo I think will have greater resonance in the last episode. Tyrol says Boomer, Athena, (and another name I can't remember) they're all the same, because we made them all the same. In a negative sense, this means that they can't be trusted. But in a positive sense, it means that if all the 8s are the same, then they will all feel that emotional conflict, and that love for Hera, which would explain why Boomer was crying, after handing Hera over to Cavil. There's a possibility that her love for Hera will conflict with her loyalty to Cavil, and she'll fight to save Hera.

In terms of Roslyn, this was the first time I've really understood and sympathized so fully with this character. I completely agree that it reveals how tragedy has led her to the cold, distant place she occupies as President. Her Christ-like pose also resonates with Baltar's Christ-like pose when he first understands that he's an instrument of God. I read somewhere else a very interesting interpretation of their relationship. Roslyn's destiny is to lead the people, to save them, but in the process she loses much of her humanity. Baltar's destiny is the same, but in the process, he gains his humanity. (I wish I'd thought of that lol).
On Anders, it struck me that as he speaks, and like the other hybrid, he sounds as though he is orating poetry, or the lyrics of a song.

I disagree and let me explain why. In the previous episode “Islanded in a Stream of Stars”, they made it clear that there was no way to find Hera now that Cavill had moved the Cylon colony to an unknown location. The scene where Helo pleaded with Adama (a man who knows what it feels like to lose a child) to let him take a Raptor so he could try to find his child was meant to reinforce that sense of despair that there was no way to find Hera. And yet, from the perspective of the audience, we knew they would find a way, that they had to if they were going to wrap up all the major threads still left unanswered. And clearly as Hera appears to be the key to all this, it’s simply not a plot detail that can be so easily glossed over. Besides which, they had in this episode the perfect opportunity to reveal such information within the context of the series mythology. Here comes my elaboration on how that could’ve been done.

First of all, remember that at the start of last week’s episode, Adama was clear about his having “it up to here with destiny”. That’s pretty much in tune with Adama’s character because he’s never been a part of this metaphysical element that’s been coursing throughout the series. So, it’s only natural for him to not put any stock into this since he’s never been a believer of it. That alone makes it hard to understand how Adama would know, over the Final Four and Kara, what question to ask Anders or to trust that Anders would even know the answer.

The second point to recall is how Kara decided at the end of “Someone to Watch Over Me” that Anders was the key to figuring out what’s the message behind the song “All Along the Watchtower”. In terms of the series mythology, this song has played a significant part – it re-activated the Final Four and it helped them find the way to Earth. In last week’s episode, we see her sitting by Anders’ side trying to come up with all sorts of mathematical possibilities that might translate the music notes into something useful, although interestingly enough, she’s disconnected Anders so he’s not really ‘conscious’ and thus able to help her.

And now, here’s the punchline for what should have happened – when Adama arrives to seek help from Anders and Kara, he should have asked Kara to re-plug Anders but not have a clue as to what to do next. Again, this character has been on the outside of this whole metaphysical side of the series mythology and he should feel like he’s grasping for straws here, as opposed to having a clear idea of what to do next. As I wrote above in my review, the reason he now wants to save Hera is because he realizes that she deserves the same chance as he’s given everyone else in the fleet, of having him come to their aid. After Adama admits to Kara that he doesn’t know what’s he doing there or what he hopes to accomplish, Kara starts inadvertently humming the notes she’s been staring at all this time. After a point, Anders reacts to this and his nonsensical rambling turns into a clear indication that he knows where Hera is. Not so much a list of co-ordinates, but perhaps Hera’s name and a cryptic remark about ‘skirting the maw of a giant’. Kara and Adama react to this, with Kara asking Anders ‘Sam, what did you say?’. And we cut the scene and the episode continues as seen last week.

See, this way, we realize why Anders was able to give this information because, once again, it ties back to this song and its clear significance as the source behind how the events are being revealed. We don’t have to understand why hearing this song gets Anders to locate this information since we’ve already seen how it caused the Final Four to realize their true identities as well as locate Cylon Earth. Having it also tell us where Hera is would hardly be much of a surprise at this point; indeed, it would fit into the puzzle they’ve created so far very well (of course, I’m expecting the explanation for this song’s relevance to appear in tomorrow night’s episode as it’s too integral to the series to be overlooked). This would also build on the repeated idea that Kara Thrace is the harbinger of death for the human race. By having Kara’s humming the song be the key to unlocking the location of where Hera is, she becomes the reason why they can now go after Hera and ultimately face whatever human cost they will suffer in tomorrow’s episode.

This is why I found the reveal of Hera’s whereabouts disappointing as they had a clear set-up in place to they address it and add to the importance of this song while at the same time, maintain the characters in their positions with respect to how they’ve dealt with this whole “destiny” notion. A little tighter editing and an economy of words would have allowed for such a powerful moment that would lend itself to the ultimate tragedy that this series will inevitably have us face.

To be honest, I'm glad that we didn't see Tyrol getting in trouble…again. For me, it worked that we saw him in the brig as a result of his actions. Over the past 4 years, we've seen plenty of times where Tyrol has been dressed down by Adama or Roslin and with everything that happened in the episode, I think it would have broken the flow of the episode.

As for seeing Anders…eh. Again, I was ok with not seeing the scene where he reveals where the location of the colony. I don't see it as a significantly important part of the episode and appreciated that the editor didn't feel like we needed to be lead from Point A to Point B by the nose. It was enough that they said that he let them know so we could get on with the rest of the stuff. Then again, I've never really been a fan of the Anders character so that may have played into those feelings a little. ;D

You bring up a good point about Helo and Tyrol bonding earlier when they attempted to save Athena from being raped. That fact should have weighed heavily on Tyrol because, as he states in this episode, he now sees all Eight models as being the same. Had they taken the time last week to address this, perhaps the short scene here between these two would've felt more significant than to merely point out that Tyrol was among the people pardoned by Adama as a way to gain numbers to join his mission to save Hera.

I do think Roslyn's flashback scenes are necessary (except for the one where she gets the call about the blind date – that really didn't serve much purpose since we already got in the previous scene her transformation into the Laura Roslyn we've known from the start) because it's important that we realize that she wasn't always this way and her willingness to open herself to her feelings of being content is not a change to something new, but rather a return to who she really is behind that facade she's been wearing all this time.

Good job spotting the point of Roslin's Caprica flashback. I couldn't find one. I still don't think it was worth the time, but at least they weren't just giving McDonnell something to do.
