Forrest wasn't late, not really. He was just... a little late than normal. But that was fine, right? Since the class hadn't started yet... right. He knocked on the door, open or not, and quickly found a seat at the back rows of the class. He [/s]was afraid of the Professor so he[/s] didn't greet the Professor, because that might distract her from her concerned looks?

Yeah. He didn't sit though, because Professor liked it the old way.
