Lancelot is so busy trying to make sure nothing else is floating (and quickly snatching them to stop it) that he doesn't realise Faolan is falling until he hits the ground. He winces sets the cushion down and reaches out to offer him a hand up again -- eyes still flicking around in paranoia.

"Come on," he encourages, "we need to get you sitting down somewhere. I'm afraid you're going to have a pretty bad hangover after all this."

If he's falling down drunk then really, there's no hope of avoiding it.
