James - James is super chatty, so I'm not too concerned about him getting lonely. Get Harry ready for the infodump! James gots de infoz!!
Ted - That makes sense. He also met Ted once, in Ted's future. He and Hagrid landed in his and Andie's garden at the battle of the seven Potters. Ted helped patch him up (if you want him to recognize him, he can).
Hermione - What can I say? I have a type! (Just wait until I pick up Bellatrix or something...) He risks getting cried on by postpartum Hermione with mean words like that!
