2B nods in agreement. A routine maintenance check sounds like a good idea. That's a good idea, Operator. Proceed.

While 6O is doing her maintenance, 2B observes her Operator's actions. It's unusual for 6O to stick so closely to protocol. After a while, 2B asks 6O. "Are you alright?"

Somehow, it's easier to express herself in her own head. Words that are usually stuck in her throat flow more easily during maintenance.
