Levi seems to agree to stay, and it's a relief. He watches with slight confusion as Levi changes. While it's certainly normal to wear more comfortable clothing to bed, the act of wearing Finnick's shirt with no pants seems overly familiar for someone like Levi to do at this point in a relationship. The fact that he's doing it for cleanliness reasons is lost on Finnick. Either way, it's not like he minds. He grins as Levi climbs into bed, both because he's very cute dressed like this, and because Finnick is delighted to share a bed with him. He scooches himself as close as he can.

"Just one more thing, sorry," he murmurs. He lifts his metal arm up from under the blankets, toward Levi.

"Will you take this off for me? There's a button there to release."

It'll be hard to get back on himself later, but he'll either ask Levi or Night Sky to help him. For now, he wants to be comfortable.
