My friend has a crush on "Two Face" from The Dark Knight. Should I take her to see a psychiatrist?

She made her bf paint half his face red and then had with him. She even has a little Two-face doll (I think she made it herself from a Ken Barbie doll..creepy) and campaign posters all over her bedroom walls that say "I believe in Harvey Dent". I'm a bit freaked out..HELP?
