Strange is gatecrashing the 'get his trailermate drunk' party a little late. Because he saw that Lambert was shoving the faerie ale on Syrlya and decided that the best thing to do is get something a bit less potent that would go down fairly easily.

So, he's walking over to the two with a half full bottle of the sunlight ambrosia and a glass for Syrlya. "Try this one," Strange starts, as he offers the bottle to Syrlya. "I guarantee you, it'll go down much smoother than anything Lambert forces on you."

Which is entirely the point. The drink goes down smoothly but hits hard later. And really, if they're going to get Syrlya a bit drunk, might as well get him drunk on the thing that isn't alcoholic paint thinner.
