Satrakian’s (can't think of his real name!) part in Harry Potter was small, but he was in all of them. He acted like he hated all the kids and was only there to get them in trouble for sneaking out of class or their rooms, and he always had a pet cat, but in the end after all 7 movies you see he always had the kids best interests at heart. :)
Oooh, I never thought about Fet having to take over if something happened to Setrakian, but you’re right. Eph wouldn’t be the one to do it, being the science end of the whole deal.
I can totally see Setrakian playing a grouchy old wizard with an actual heart of gold, lol. He seems so lovable to me, and the sandpaper voice and the impatient manner tickle me.
