Dory is kind of a sad character (possible spoilers)
It's sad that someone has so little of a life that they put all of there energy and hopes and dreams into finding someone who took off on their own. She barely knows this chick and she's chasing her like she's a family member.
Something else that bothers me about Dory is how intrusive she is. She's so dead set on creating some drama in her life she doesn't give a crap who's toes she steps on in the process. This make her very unlikable and quite dumb IMO.
I hate her weak bf, ugh! Nothing turns me off more than a weak a$$ man. And Dory's self worth is so low that she settles for that tool. Like I said, she's sad.
