It doesn't take Nik long to show up. He remembers where Equius' room is and this time he's excited to actually meet Equius' roommates, since he hadn't gotten to last time.

When he arrives, he stands up on tip-toe and reaches as high as he can to knock on the door.

And, because he knows he's a little too short to be seen from the peephole, he also calls out to make himself known. "Hello! It's Nikolai."
