Having already talked about two deaths and now his mention of joining up, it's hard for Lexie not to think of George and his plans to join the army that preceded the accident that killed him. There are days that still hits her, too, more frequent since he disappeared from the island (she never told him, she never told him and she should have, could maybe have prevented it from ever happening, if not in her own timeline than in some other. If being here has proven her anything, it's that these things can be varied, and she might well have sent her best friend to a death sentence). She takes a deep breath, though, smiles and pushes it down like she's been doing for so long. "Who'd you join up with?"
