She's fine with Solo but probably steamrolls him accidentally from time to time.

Nah, Ophelia's not really a mean girl, per se, and isn't much for mocking people. Well, not girls anyway. She might mock boys. She was Popular at Hogwarts, and... wants to be popular at Gooseberry too but we'll see how she unfolds. But yeah Eve could totally have been one of the Gryffindors who snuck out with her to explore the Forbidden Forest. I imagine they got in a ton of trouble for that.
