"I don't know." Sam had sorted of hoped that he would. It'd be a lot easier than having to see Dean have to process everything that had happened in the past year all over again. Seeing him do so as things were happening was bad enough as is; to think that he'd have to take everything in all at once, with little to no idea as to how things happened to begin with? It wasn't something that Sam was looking forward to. He was almost ready to consider giving it the old patented movie trick, what with fictional characters getting memories back by being bonked on the head one good time. The literal version of one getting sense knocked into them, Sam supposed. Too bad the movie version was nowhere near what would happen as a result if Sam tried to pull through with that kinda thing in real life. "I thought maybe you might start remembering a thing or two after a couple days, but..." No dice, it seemed. Sam pushed a hand through his hair and frowned.
Do I even want to know everything? Sam was barely able to suppress a wince at that. No, Dean didn't want to know everything. Sam half didn't want him to know everything either. It'd be easier to let him just...go on. Get used to the fact that his family was alive again, focus on all those issues that had followed him up out of the pit. That stuff. Not any of the tremendous screw-ups that Sam was responsible for or any of the other crazy scenarios that they'd dealt with around here in the past year. Not knowing was better. "Probably not," Sam admitted carefully. "I'm not gonna lie to you, Dean. This past year hasn't been easy on much of anyone. Especially you."
Sam reached for his glass again. He didn't drink any, but he felt like he needed to be doing something with his hands. "Honestly, I'd rather just...not. But I promised you that I would, so. I'll fill you in on anything you feel like you need to know. Then, I guess, I'll help you fill in the gaps from there."
