The body is different than he remembers. The insignias are still present, true, but the scars and circuitry -- Hypatia has changed so much.

He'll just have to get to know him again.

Gently, he nudges and guides Skyfire to crouch on the portion that is a brick floor. About as sanitary as he can get it to be.

For a moment, the Decepticon is gone, if only to heat up a bucket of water and fetch a sponge. Not long after, he approaches, rolling up his sleeves.

The sponge is dipped into the bucket and he leans in close, slowly scrubbing in small circles over Skyfire's back.
