Patrick would have been very nervous but outwardly calm while walking Hannah down the aisle, and helped her calm herself to keep from skipping or running (although in truth, if she'd done that, he would have grinned and maybe applauded before awkwardly looking around and trying to get to his seat before he accidentally got in the middle of the ceremony). And he probably cried a little. He also brought a present... but I will have to get back to you on what that is in a moment. :D
