I'll need to send him a message, too.

Don't worry if you've never got on; something like this happens, and you just set it aside. He'll appreciate hearing from you anyway; I know he will.

If they've just found out the news today, they're probably preoccupied with family stuff. It won't be thought strange at all if you wait to send a message to him. Especially if you were there. So you have a little while you can use to sort out what you should say to him. At least you can tell him that Percy was always decent to you, yeah?

I'm awfully sorry, Seamus. That must have been awful to see.
