Ivan had been outside smoking a cigarette - he's here mainly because he is not past wanting to keep Ilde mainly in his sight, and she wanted to come - and he's far enough back that he doesn't have to move at the abrupt landing. He certainly notices, though. Thor is a hard person to miss.

He also remembers him from the Network as running afoul of Daniil's distaste for rising abruptly or early.

So when he passes, Ivan offers a mild, "You do make an entrance, don't you."

Some people say hello, Ivan.
