Nico's gone days without speaking. There are times when it's good to have someone around who will break those silences, but he's not uncomfortable - he's not made more uncomfortable by her long silence. He does note it, to add to the rest of the things he's observed, but those observations are automatic.

When I'm around a lot of people... there's so much and it doesn't stop." The sensory overload can be a lot when he's outside, even when they aren't people around.
