I completely agree with this topic. While Fi may not repeat two lines of audio throughout the entire game she makes the goddamn remote in your hand beep. Constantly. I know i'm out of the hearts! the television is telling me too!

She is a complete waste of a companion and has little to know character. her singing however, is hilarious.
