10 TV Characters Who Disappeared Without A Trace

4. Tom Milligan - Doctor Who

After the Master takes over the world, Martha is sent on a mission to walk the earth for a year, telling people of the Doctor so that he can use the powers of their good vibes and resurrect himself a la Jesus Christ. Along the way, she meets another doctor, a kind-hearted, devastatingly handsome young man by the name of Tom Milligan. They have a brief connection, and Tom gives his life trying to protect Martha.

After the world reverts back to its former self, Martha decides to track Tom down, seeing that he's not dead and all. The next time we see her, she's glowing and has a ring on her finger. Finally, Martha has the doctor that she deserves. But then when she shows up in Ten's very last episode, all of a sudden she's married to Mickey. They're a cute couple and all, but...um, guys? Where did Tom go? Why even bother writing this whole subplot about her finding him and them falling in love if Martha/Mickey is endgame?

Putting aside the fact that Martha and Tom were adorable together, it's kind of silly to think that all of Ten's former companions need to be neatly paired off with one another. It wouldn't have taken anything from either character to keep Martha and Tom together, and it certainly would have been less jarring.
