Having found the same hub, it took all of five seconds for Sentinel to realise that he lacks the technical know-how to perform the repairs required. That, and his hands are about 500 times too big even if he did know what to do. It's... nice to see someone else, he finds. Sentinel is nowhere near a personable mech but being stuck in a deserted city with literally no-one else is a bit much even for him.

Well, if it walks like an Autobot, has glowing blue lines like most Autobots and is small enough for him to punch into orbit if it tries to attack him (like most Autobots)... Sentinel approaches slowly, regardless.

"Have you been here long?"

Yeah.

Nailed it.
