Took the blame for Sarah's picture - Because things were tense enough without her getting yelled at over something like that. Also, I'm starting to get the impression that she might be mentally handicapped somehow, with the way she looks much older than Clementine but acts so much younger and naive. So I feel like I have to look out for her.
Sat with Kenny at dinner - Because come on. I thought the dude was dead, we got a big happy reunion to do. Luke can deal with it.
Told Walter the truth about Matthew - Because lying was obviously only going to make things worse.
Convinced Walter to forgive Nick - Even though I'm not entirely sure I can trust Nick's mental state anymore, the last thing we needed was more people getting killed.
Surrendered to Carver - Because I honestly thought Carlos was going to die if I didn't. It didn't seem like there was enough time to try and find Kenny or Luke.

Good thing I did, too. Turns out if you try and sneak out then Carlos makes it out alive but Alvin gets killed instead. So with both Alvin and Nick saved I managed to make it out of this episode with the lowest possible body count. Go me.
