She was going to miss him too. His insides warmed at the thought. "We'll keep in contact," he decided, squeezing her hand firmly, "it'll feel like we've never split ways." Not really, but words of reassurance were needed while they were still here together now. He didn't want to dampen the mood that they were thrown into with talk of the future.
Sam's mouth briefly fell open at her questionable repeat of the word. He slowed up in the skating, hand slipping away from her own so that he was able to turn around into a position where such topics wouldn't literally throw him off his formerly backward balance. "That was - I mean, demon friend. Who is a girl. That I happen to be in love with." Someone skating by just then must have overheard the terms 'demon', 'love', and 'girl' because they paused in their stride to look at them both in confusion. "We're religious. It's...a debate," Sam explained. That appeared to be enough to satisfy the intruding party. Sam let out a sigh of relief, the visible cloud of breath escaping his mouth making the reaction that much more notable. "We've really gotta come up with better nicknames for all this stuff we get on about."
Sam liked showing her off too. He almost wished that he had the nerve to fess up to things as far as where they stood to Dean and, quite likely, Bobby so that they would no longer have to hold back. But at the same time, it was better that they had their privacy. It made the extreme debates and arguments that were likely to follow nonexistent.
