Mr.T was still nervous about the door. He didn't know what could be beyond that door, what monsters or people or some hybrid of both, that could be lurking around elsewhere in the house. Mr.T was terrified but he thought that as long as he stayed with the group he would be able to get back to Dexter. When the fairy went up to the door Mr.Teddy stared at her for a bit. He remembered Dexters mom telling stories to Dexter about fairys and all of their magical powers so just seeing the fairy was amazing for Mr.T.
