The surprise was to be expected, that moment where it was clear that Kakashi was weighing the likelihood that Sasuke was telling a lie. Anything deeper than that -- what conclusion the man had drawn in the end -- was hidden beneath the mask and the forehead protector covering Obito's eye.

The information made no sense to Sasuke, however, his brow furrowing in confusion. "Coming to get me? From where?"

Kakashi showed too much caution with him to be from any time earlier than his defection from Konohagakure, and if he had to place an age on him he would guess he was a older than that. It couldn't have been the one time his former team had managed to infiltrate Sound -- Kakashi hadn't been there as far as Sasuke had noticed.
