It really is, to be honest. It continues to be rather infuriating, Karen would really like to give whoever was responsible for him a piece of her mind. She's glad she can be so helpful, though. Still -- she probably can't do this every weekend, for sure, and probably shouldn't commit to more than one of these a week. She should figure out some way to help him learn these things on his own at some point, if he's this adept at learning them he should be able to. Though she probably should do some reading on what's involved with teaching that sort of thing. And help him get caught up on the rest of what he's missing, also. And today probably isn't the best day to talk about it either, given that something seems to be going on with him. Maybe Wednesday, as long as he's feeling better. Hopefully that useless professor doesn't assign him yet another quiz next week like this one.
Eventually, when he's not asking for clarifications, her mind wanders back to her problem, trying to get things in the right shape in her mind. And then eventually, he's done, and she checks over his work. There's a couple of minor errors, which she points out, but nothing that implies he doesn't understand what he's doing -- clearly he's learned all of what she was just teaching, as well as everything else.
"Well, as long as you do this well tomorrow," she tells him, "I'm sure your quiz will go fine." She grins, happy to have helped. "You've got nothing to worry about."
She looks at her phone. "We have a little time left -- we can go over some other math stuff to help you catch up, or call it a little early, get some campus food, and then talk about what you want to talk about? As long as you still want to!" She finishes, quickly. Having an hour and a half to get used to the idea, she doesn't mind so much having to do this. She's still a little attached to the idea of heading back, but she wants to make sure Sean is ok -- as a friend/caretaker of some kind. She really wants him to flourish here, it isn't fair what happened before, and depending on what's going on, maybe she can at least be a friendly ear.
