Niverian is in the middle of doing some repair work on his ship's engines when he gets Purple's message, so he's able to come pretty much immediately, only needing to get cleaned up a bit and change out of his greasemonkey clothes and into his uniform before heading over. He definitely gets the impression that this is not for a date or anything of the sort.

That doesn't stop him from greeting Purple the way he usually does, though: with an embrace and a gentle, lingering kiss on the lips. That done, he glances between Purple and Winston for a moment, and asks, "So, what's going on?"
