Finn was walking through a long corridor when he passes by you. He didn't seem to have much of a reaction, but in his head he was wondering about you. You seemed like a new fresh face to everyone, so you're probably new, he thinks.

Later on when you get to your dorm, you see that he's your roommate. What are the odds? O-oh, I didn't see you there. He chuckles nervously I'm Finn Ames, and I'll be rooming with you this school year. Pleased to meet you. He bows politely. He wasn't as nervous meeting you for the first time compared to meeting Mash, maybe you were just easy to approach.
