Not Roslyn. She is probably being affected either by the transfusion from Hera, the kamala she's taking that gives her funky visions, or both. I'm very curious about the power outage thing, though, and her coincidental weakness at that time.
He didn't steal the Viper. Granted he wasn't assigned, but rules are lax, there was the power outage and Cylon appearance, all was chaos, and anyone if asked would surely agree that they needed any qualified pilot. Probably including Mr. Agathon. Lee gave a thumbs-up to the launch supervisor, he's not leading the squadron, and he called himself off when he went to check out the bogey. I'm not sure she showed up only on his dradis, either - could just be everyone else was focused on the obvious enemy presence.
One overview I saw of the episode noted the irony of the look at the end between Tigh and Tory, affirming their allegiance as the right hands of the most powerful humans in the fleet even as they were digesting their own shocking revelation.
Timberwolf has an interesting idea there and one I've not seen or considered previously. I doubt that's actually it, but there could be jewels there.
I thought it was a great episode. A lot of mediocre episodes this season, but this was really, really good. Tigh's speech ("...and if I die today... ") and Lee's speech ("It's about shame!") most especially stood out.
Some questions about these four being Cylons:
1) Tyrol & Callie's kid. If he's a Cylon, then the kid should be like Hera, if it's his.
2) The ones with the fleet at the time did not seem to be affected by the radiation in the nebula with the armory in the pilot episode, as were the other Cylons.
3) First-season episode "33" had the humans tired enough for walking dead, except Boomer. We know Boomer was a Cylon. Tigh and Tyrol were pretty haggard. I believe Tory was too. Sam was still on Caprica. Someone pointed out that Tigh did give up one of his 30-minute rest periods to Adama ("If the Old Man can't remember, it's his turn.") but I don't think that's conclusive.
One of this season's episodes, when Baltar was with the Xenabot, they talked about the Final Five and he was told they were "fundamentally different." Anyone have that ep recorded? I want that dialog, darn it! It was obviously prior to "The eye of Jupiter" but I don't remember which one.
Porsche, thanks for starting this. I was going to but you beat me to it.
BTW, if you didn't know (and I didn't) that song they had so much fun with in that ep was "All Along the Watchtower" by Bob Dylan. Also done by Jimi Hendrix and others.
