Otto had just arrived on the recruitment office when the two recruits left with not so much color on their skin as he had on his palm. He stood 1.73m tall, and about a third or a half of that on width. Probably larger than the two of them, he stood by, watching them leave, and as he turned his small eyes toward whomever stood behind the counter, he was met with a simple gesture to wait.
Otto wasn't exactly "fit for fighting", by Sirius standarts, but, maybe for the first time on his life, he was damn sure of what he was doing.
Quite unable to hide his anxiety, he sat down on the chair closest to the door.
