If you have Lute from Fire Emblem the Sacred Stones and you have Lute, Artur, and Kyle both have Support A in the game, check the ending. She'd probably marry both of them because she's a cheater!!! She loves both Artur and Kyle!!!
Kyle: "Who do you like? Me or Artur?"
Lute: "I don't know!"
Artur: "You have to choose!"
Lute: "I like the both of you!!!!"
