Sophia'd been there for a while now, given the time it took Tavish and the rest to get to the police station, look over the contracts, launch himself back, and buy the booze. She was working the soft would with the nail on her left thumb, it was slightly longer than the rest. The sculpture complete enough that Demoman could tell that she was making the playground there.
With Tavish coming downwind of Sophia, she wouldn't smell him coming.
(Is Tavish still really hurt from the launch from the stickies?)
