Spoiler:
The actual answer to the last conversation is...
1: Hey Moloch, do we have room for one more stray?
2: Yes, what class?
1: Not sure. Never seen one like it before.
1: This one.
2: Oh no. It's that annoying Y1 again.
3: The one that keeps controlling the scraps?
4: Real special that one.
2: I'd say destroy it, but we need the parts.
2: Put it back downstairs. As far as you can.
3: And lock the doors behind you.
4: Yeah, lock real tight.
1: Alright.
