Emil is staying in Locke! He has a job (and school but let's face it he doesn't take it seriously) He's going to have a lot of silly monster related shenanigans. Gum and toothpick probably, maybe brush too.

As for echoes, he's getting back his horn and his violin. The violin that has missiles hidden inside. He's going to use it to fight monsters so if anyone wants a (really stupid) teamup?
