It was definitely an option. Both were definitely an option. David had an extremely biased preference for working through it with Syd, but in all honesty... he wasn't sure how he felt about trying. This was who he was, for better or for worse. "Thank you," words soft, smile rueful. "I'd do it with you, I'm just not sure it's such a good idea." It'd probably end up the same way, in a sense. "If I could still be with you--" A sudden, crippling shame hit him and David looked away, looked down. When all of Syd's hair fell in his face, it was tucked behind the ears without much thought.
If he could still be with Syd, he'd much rather be normal. If it meant still having a future, not having to be involved in this stupid war, Syd being safe from telepathic invasion due to lack of being involved? David would go for it in a heartbeat. The chance to be a better person, to actually deserve someone like Syd? Yeah. Definitely preferable.
And unsafe thinking, so best not go down that rabbit hole.
The return gesture, going for the nose, brought laughter though. This was the situation now, face poking as their bodies had swapped and they had the chance to find amusement in it. Poking each other, poking themselves. "Guess we should. For science." Something to mark down, another learning experience. They could find out if Melanie did really think that or if Oliver was just playing it cool like the Cool Cat he was.
"Well shucks, I love you too." David linked their hands together again and used it as a means to tug Syd up again. "C'mon. Let's check in on Melanie first, see how she's doing face-to-face. Maybe we'll switch back on the way." So might as well enjoy the hand-holding for just a little bit longer. If it'd almost been two hours of wandering, chatting, hugging, playing piano... my how time flew.
