Rose (portrayed by Melanie Lynskey) is another character from Two and a Half Men, she's Charlie's neighbour. She and Charlie had a one night stand a little time before the series started, and during this event we are to believe she glued his testicles (he still has the bald patch, and the comb over is fooling no one)) to his thigh. Rose has been stalking Charlie ever since. Her father is portrayed by Martin Sheen, the father of Charlie Sheen (who portrays Charlie Harper), when her father had sex with Evelyn he started stalking her just like his daughter stalks Charlie. Her family is also quite rich and owns many Banks. Their wealth is not only down to Banking, but the Oil Industry also. She often climbs the deck, ignoring the stairs. For understandable reasons, this activity is regarded as odd and is a running joke. She finds Alan dorky and annoying, like most people. Alan finds her pathetic and frightening. She seems to be the only person who's life is worse than his. She's often giving Alan and Charlie amateur therapy--like a lot of therapists, she seems to be unbalanced herself and has taken up the practice so she can self-medicate.

Rose has five pet ferrets, all of whom are comically named Charlie (ambiguously suggesting either an affection for the Human namesake, or an obvious acknowledgment of her dislike for Charlie's ways).

She also made the CharlieHarperSucks.com website in the episode "Last chance to see those tattoos.
