Majima jumps at the pinch and gives Harley a fake-scandalized look.

He takes the offered shot and raises it in cheers with a "Kanpai!" before he tips it back. As entertaining as it might be to see the rogue tipsy, he has enough wherewithal to pat her shoulder and blurt, "Oi, oi. Pace yerself, or yer gonna be drunk as a skunk."

Whatever's in those shots is already hitting him like a truck, so he can't imagine what it's doing to Amelia.
