This is not a spoiler for last night - merely a clarification of something it appears a lot of people missed back in 2-5 (Resistance) and 2-6 (The Farm). But in the interest of those who might be really behind, I will cut it.
Kara and Anders were not together just for 48 hours, but for six weeks. Several BSG fans are expressing disbelief that she could fall oh-so-in-love with him in 48 hours that she'd be so adamant about returning, but whatever was going on on Galactica right before they reunited was happening *six weeks* after that. So it's not ludicrous to assume that she developed real feelings for him.
