Since meeting Lena, the game plays on a running gag where she is confused with "Rena", apparently some psychotic murderer that I don't recognize. This ends up being integrated into her character, though, as throughout several endings she's described as inexplicably having a knife handy, and/or, well, murdering people... despite being the sweetest wife ever in her good ending. Anyone got the name for this trope?
It's probably yandere you are thinking of, from the anime fandom.
