Aye, I could say the same about you. Whatever was in that drink makes it so I can't think of anything but you but...I don't want you to think it's just the drink. You're beautiful without it, all right? I wouldn't need it to find you beautiful.

( Jon feels like that's important to say because if Eirene thinks that he only wants her because of the drink they'd both indulged in, it might make her think poorly of him and he doesn't want to leave that sort of impression. )
