"What do you mean by that? I'm pretty damn sure I'd recognize You anywhere." Leonard replies with a snort. It's dismissive, but carries an undercurrent of concern for the bold statement. He can't deny there's a whole lot fishy with Spock's arrival here. From his outfit, to his Much less stand-offish demeanor, to just the ease at which they're communicating.

The Spock he knows knows literally absolutely No human idioms or customs whatsoever and is the cagiest bastard Leonard has ever met. Gets along alright with Jim, but anyone else? Might as well be ants under a microscope. Yet talking to Spock now is...well it's still awkward but it's markedly different.

"Which one of us is the doctor here?" Bones grouses, but he does acquiesce and turn the tricorder over. He's got no baseline to compare these readings to. Spock at least should know himself one would fucking hope. "Fine, here. Maybe give me some idea of what these Should be while you're at it."
