Adam Mitchell 

I made the “Doctor’s male companions” post and i remembered Adam Mitchell.

One name, one huge missed opportunity

He met the Doctor, the Doctor then decided to take him (happens rarely) in the TARDIS and next episode he gets kicked off because of his bad behavior. He kicked the opportunity of a lifetime and in some cases more than one lifetime (Jack) just to make a hole in his head. If you dont call this lame how do you call it?

When i think about him i get so angry because there are people who dream of traveling with the Doctor and most of them would leave everything behind but Adam used the Doctor for his own greedy benefit.
