When Bertolt describes the way Mikasa had (or will, from his point of view) attack them both, going as far as to injury Bertolt, Reiner narrows his eyes, instinctively raising a hand to splay his fingers out against the side of Bertolt's neck where her blade had bitten into his skin. Of course, there is no mark of it. They heal quickly, and he knows that for Bertolt all of this is a year in the past, but that doesn't stop him from moving as he does. He had already lost one friend through his own inactions, and he did not care to make it two.

Letting his fingers linger against Bertolt's skin, he listens to the rest of his story, his expression darkening when Bertolt mentions Annie's fate. Annie and him did not see eye to eye on the best days, but she was still one of them, a comrade, and the thought of her trapped behind those walls, in the hands of the MPs or the Survey Corps is one that sits heavy and uncomfortable in his stomach.

His hand slides down after Bertolt's final words, squeezing his shoulder for a moment. "I probably would've done the same thing. Shit, we both screwed up, didn't we?"
