It's only a matter of time before York and Maine and everyone else realizes he'll never be as strong or tough or capable as them. Of course they'd abandon him. Of course. Wash's hands curl into fists, and if not for the cat, he'd punch his other self in the face.

"Takes one to know one," Wash says, cooly, and turns to leave. His other self can be abandoned one more time. See if Wash cares.
