Here’s what I think we’re going to see in the Battlestar Galactica finale. If you haven’t seen tonight’s episode (“Islanded in a Stream of Stars”), you should watch it first. To give you a little spoiler space, I’ll start with some of the less specific stuff, including the big one, #1, which is something my girlfriend thought of last year and is looking more and more likely.

1. Death turns out to be the way to a new home for humanity and Cylons alike. They will break the wheel of fate and end up in what amounts to Nirvana. Kara has already done this and come back for everyone else, but she doesn’t know it yet. Perhaps Caprica Six and Gaius Baltar have done the same, and the versions of them we’ve been seeing are “dead” in whatever sense Kara is dead. When they get there, they’ll encounter some characters we’ve known to be dead, including Dee and Zak and maybe even Billy. This is how Kara can be “the harbinger of death” and “lead humanity to its end,” but actually be doing everyone a favor.

2. We’ll see “our” Earth — the planet at the end of season 3, which the clever frakkers at galactica-science.com have been telling us is different from the “Earth” everyone landed on and found a charred cinder in the middle of this season — the home of the Final Five. As that website has predicted, it will turn out that Cavil has brought the incredibly-cool-looking Colony to our solar system. I didn’t think to look closely tonight, but it’s probably either floating in space or it’s on, like, Mars or something. I’m not sure how this theory works with #1, but they both seem likely.

3. Adama is going to ram Cavil’s Baseship with Galactica, or maybe even the Colony itself. This was not-so-subtly foreshadowed by Hera playing with strategic models at the beginning of this ep, as well as the painfully dragged-out talk of Galactica “dying.” What’s less clear is who will be on board at the time. Probably Anders has to be, but maybe Adama will stay too. Roslin might even stay with him, but then again she’s got to show up for the Opera House, either physically or mentally.

4. Boomer’s going to betray Cavil and help Hera escape. Boomer betrays everyone, after all, though I just can’t bring myself to hate her. She’s a sweet girl, but everybody uses her except Tyrol (her “dad” — sorry, not really buying that rhetorical line). She’s a super-terrible mom-substitute, but when she calms down and starts to treat Hera like a little person, you can see she has a heart. And Hera has to make it to the Opera House.

5. I’m not sure what to make of the so-called “head!characters,” or “angels” as I think we have to acknowledge them. I think it’s significant that the only people who have seen them, as far as I can remember, are Caprica Six, Baltar, and Kara Thrace, which is partly why I’m speculating that Six and Baltar truly died in the nuclear blast and that only the undead are seeing angels. But then apparently the Final Five saw them too. So are they “dead”? Or did they just resurrect in the non-Cylon (according to Baltar) way that Kara did? In any case, I’m wondering (as others have been) whether the Six and Baltar in the Opera House are in fact their Angel versions. Seems likely.

That’s all I have so far. What do you think?
