"Okay." The Soldier starts by prowling the whole space, securing exits, examining windows for proper locks, looking for bugs. Gold has enemies. It stands to reason his personal space could be in danger and should be kept secure.

Only once that's complete does he consider any need of his own. He glances between his hands and Gold's shoulder, or thereabouts, trying to discern if that was a hint that he stinks or looks messy, or if it was... human-type-person being polite. He decides to err on the side of caution and slips into the bathroom without another word to at least wash his hands and face, and splash some water on his hair, just in case. At least he knows he's not got blood anywhere. He'd been careful to be at least outwardly presentable before approaching his new handler.

He doesn't linger at the mirror. He's not fond of mirrors. Looking at his own face is uncomfortable. He just comes back out, following the smell of food to the kitchen on the far side of the room.
