I thought this episode was good. I really felt for Peter Mills. I really hope he stays with the team. His mom is just making it worse for him. Telling her son that he needs to quit, is just wrong.
For Severide I think he needs to tell someone about his shoulder and quick. With Mouch and the Canadians, that bit was funny and the Canadians getting Otis back for the prank he pulled was just funny. This show is getting better and better. I hope this show keeps going and going for many years.
