Same ward
Your dad? That's a big one, isn't it. If you find him and don't like him or find out he was a Death Eater or something, then it's really awkward! And if he's brilliant, then it would all be worth it, but what if he isn't, or he sort of is but is also a jerk in some ways?
What do you want to do? Only you can make the final decision on that, mate, but if there's anything I can do to help, let me know.
