Jack Harkness is
Juvenile, he is such a big kid
Attractive, so so so hot, if you do not think he is attractive you are weird
Cocky, but we love him anyway, even if we all want to kill him at some point
Kinky, he has to be
Honest, but sometimes it's best not to know the truth
Angry with the universe, after all he didn't ask for this
Reckless, but he can afford to be, after all he can't die
Kind, he's helped so many people, but no one really helps him
Normal, at least he wishes he was, bit hard to be normal being immortal and everything
Egoistic, but we love him, and he has to be egoistic to be Jack
Serious flirt, but he wouldn't be Jack if he wasn't
Sexy, oh sooo sexy
