Not letting go is fine by Sylvain. Seems they're both making up for lost time in some way. Sylvain's years of pining all coming to fruition makes him want to hold fast to it.

If he does notice Felix's clothes, it's mostly that somehow they're still so similar. Something about that is terribly appropriate. In the same way that Felix still smells the same too. All pleasantly familiar.

"Hey, I'm gonna set us down. Not letting go," he mutters against Felix's neck, and carefully takes a knee. The other's weight is hardly an issue, but Goddess knows he's exhausted on all fronts. He never did get a chance to rest after the battle for the Imperial Palace. He utterly refuses to budge on putting Felix down still. So he ends up sitting with Felix folded into his lap, and stroking his back.

"Y'know, I really wish I'd done this sooner. Like how you fit against me."
