Billy is almost immediately beside himself with worry. His first meaningful opportunity to meet an android in a while comes up, and what does he do? Hurt him. He sees that thirium leak and cringes a little.

"No, it's all right. I'm a little tougher than I look, but you're leaking thirium," Billy says, immediately plunging a hand into his backpack. "I don't have any specialized repair tools with me, but I should at least stop that."

He has a bandage. It's built for humans, but it might do in a pinch...it's offered, along with any other clean cloth he's carrying.
