At most times he is the exact opposite of Cam which usually causes disagreements. Cam acts as a counterbalance to Mitchell. He appears to suffer from ornithophobia, which is the fear of birds.
Cam has been Mitchell's boyfriend for almost nine years. The two men are opposites in personality because of their contrasting upbringings. Cameron grew up on a farm, was very good in atheltics, had a supportive family and isn't afraid to be flamboyant which constrasts greatly with Mitchell's conservative, contemporary childhood. This has worked well (and challenged) them over the years because Mitchell's good sense levels out Cameron's theatrical whims and Cameron's assertiveness has helped when Mitchell shows meekness. A good example of Cameron being a strange but great boyfriend is in the Season One episode "Fizbo"; Cameron is a professionally trained clown, which bothers Mitchell, but even in costume Cam is effectively protective when Mitchell gets in a tiff with a rude man at a gas station. Cameron is often concerned with Mitchell's bad habits, such as hiding affection in public, overthinking or becoming overcompettetive, or holding onto baggage from his parents.

In doing the mundane task they sincerely remenisce on their relationship, both get on one knee and mutually agree to marry the other.

Jay has reconized his mistakes with his son and has tried to reflect better understanding with his stepson, Manny. Despite Mitchell's complaints, he learned patience in dealing with his father and strength in acceptance (though it is often forgotten).
