"Well, you made it so obvious," Ernie joked back. "And we both know I'm a catch. You'd be lucky to have me. Unfortunately, my heart belongs to one person and one only - and some day Professor Lockhart will get better and sweep me away from all this." At this, Ernie did completely lose it and nearly bent over in laughter.
Ernie took another sip of his drink before explaining further. "It really is. I don't get to use my potions knowledge much in JT, but it would be in constant use down in poisons. It's actually fun to work with them when Snape isn't breathing down our necks. Kind of like bartending, maybe - which means if the healer thing doesn't work out, I can always work for Seamus."
And speaking of which. "It was nice to have fun and dance last weekend. We don't do that enough, I think, what with work and other things. And not many people around here know how to cha-cha like you."
