So “Toby” (or whatever you are),

I don’t want you talking to Twilight anymore, got it? We already have enough weird, dangerous creatures here to deal with in our world, we don’t need to be bringing in ones from another one here!

I can send any of your letters to Princess Celestia and Princess Luna, and if you don’t leave us alone, you’ll have them to deal with!

I’m a big, scary dragon myself, and you don’t want to mess with me either, so stop it now, and we won’t have problems. Okay?

Good.
