You can't tell him what to do, Yato, he has seniority!

Tony doesn't even notice his new roommate walk in until he speaks. "Huh?" Tony looks up. "Oh, I'm not building anything yet. Just messing around with their computer hardware. It's different from what we have at home, but way more advanced than what we had in Keeliai. I can probably repurpose some of it for my armor, once I figure out how to get it to talk to my systems."

The answer is obliviously straightforward. If Yato had hoped to make a pointed statement on the state of their shared space, the nuance is lost on Tony.
