Remus
No you're not Remus. Or if you are you're not alone in that - I wouldn't have the slightest clue what to say to Harry if he came through and I'm pretty sure James wouldn't either.
And I don't think Teddy really knows what to say to you either. He's kind of made a mess of it talking to you in the past but you don't remember Would it help if I went with you to talk to him? Helped you two at least start getting to know each other? Teddy and I became good friends after I first arrived and we shared a flat for a while.
