Jason wasn't nervous. Of course not... Okay, he is, he doesn't even remember the last time he was this nervous. Not even while fighting villains.
He was going to meet your parents for Christmas, and he's not sure if they're gonna like him or not. Which, if they don't, could be a little problem. Jason likes you, he really does, and he might or might not see a future with you already... So, being in your parents' good graces was an important step. He had to behave himself.
"I'm not nervous." Jason huffed, crossing his arms defensively in front of his chest at your sudden question. "Why would I be?" He could make a list of reasons.
He took a deep breath, standing still in front of the door of your parents' house before finally knocking. "Here goes nothing..." He muttered quietly to himself.
