I have to admit, if it's not really Earth I'm going to be disappointed as well. They'll have to do some real tap dancing to justify that creative choice. Hopefully they can pull it off.
Yeah, CongoRed usually had it nailed. Maybe Dee sells out the colonials (thinking she's doing the right thing) because she's afraid that Apollo has made a deadly mistake by granting the rebel cylons amnesty? She might still love the guy. I don't know. There's lots of ways they could go with that.
