Ted Ted is a hero! He hasn't done anything heroic yet so he can find the adults/17+s. He hasn't been out patrolling too much but he will step it up once he realizes it's getting worse (...such a Gryffindor, Ted).
However I don't want him to find them on his own. I'm thinking he goes out on his own and then teams up with someone along the way. Unless he has an assigned patrol partner?
