Nico stands in the doorway, though he doesn't quite make it beyond that. He waits quietly for Holden to look up, slightly relieved to have a few more seconds to try to pick out the correct words.

In his own way, Nico's very expressive, it's just that some range of fear/worry/anxiety tend to overlay everything else so it's hard to read anything under that. He makes it a step in once Holden recognizes who's there.

"Hi." He tugs at the cuff of his jacket. He was the one who came here, he should say something. It's an even harder barrier to pass than Holden's door. "Um."
