[ The small tug does catch her by surprise, but Little Mermaid follows his silent request. She can uniquely understand what people mean without words. Not a super power, just a byproduct of a time when she couldn't speak at all. Expressions, body motions, looks, sounds. She's figured out what most of Tony's mean over their near year together. It's how she knows that what he needs most at the moment is rest, and someone to make the offer that it is alright if he simply stops for a few hours.

Ah... that's it, isn't it? Why he pushes himself without sleep ever since New York.

She not only sits beside him on the impromptu bubble mattress, but she lays down beside him on her side. Her head rests against his arm. A quietness takes over her as she asks his questions and rambles on about a lost experience from his childhood. A hand slowly raises and rests on the top of his chest. The tips of her fingers barely press against the fabric that thinly covers his arc reactor. ]

Of course I'll sleep beside you. [ As, she figures that is what he is truly asking for just with different words. ] We're magnets, aren't we? Whenever you want me to? Just let me know.

[ Then, her tone changes. Something more serious but holding that gentleness she somehow always has. ] Tony. It's okay if you stop for a few hours.

We're safe now. [ Her head tilts further against his arm and makes certain not to break eye contact. ] I'm safe. Right here, with you, in the workshop.

[ She could continue on about how JARVIS would let them know if something was wrong. Though, now she realizes the AI has been rather silent this whole time. She could mention how the portal closed and how there's been nothing to come from space since New York. Those words would be pointless to share as it would water down the point she is trying to make to him. ]
