Since we never saw Edward in the episode, I thought that it'd been a fun idea to have Thomas scare the old engine as well. The reason that he wouldn't be able to support Percy's talking about the dragon would be that he's out running trains on the other side of the Island.
I seriously LOVE this dragon.
