Chloe's one of those characters you could kill off and nothing would really be lost of importance to the story or the other characters. She doesn't really have any tight relationships with Drake (well sorta but not really), Sully, or Elena. I know she was considered a main character in UC2, but she could've been a one-off who never showed up again and it wouldn't have been a big deal. There was no reason to bring her back other than just to bring her back.
