"Hey, Spencer?" He didn't know why she was in his apartment, at this point she either has a key or has mastered picking the lock. She still comes over to steal his food and hang out even though she's twenty-two, getting married, and has her own apartment with plenty of food.
"There's this thing called knocking, Sam-"
"Never heard of it. Listen, I've got something important to ask you." Sam has a serious look on her face. This weirds him and gets him to keep any comebacks from being voiced, for now anyway. "You know how I'm getting married? Well, my father's not likely to show up and I wouldn't let him come to my wedding anyway. So I was thinking you could walk me down the aisle. You'd have like the easiest job in the whole thing and you've always- you've always been there for me, you know? If anyone deserves the job, it's you. I'd get it if-"
"I'd love to, Sam." He interrupts.
"What? Really? Thank you so much, Spencer!" Sam hugs him and he can't help but wonder how her parents never realized how great she is. He'll walk her down the aisle, because she's family and she deserves to have everything wonderful on her wedding day.
