Breaking down the door to a character class you already have

[superduperhiro]

My family and I just got the game and are having a blast. Last night I wasn't sure what to do for a situation where I was already a male Elf. I broke down the door and drew a female Elf card. I wasn't sure if I can "equip it" in my backpack to use/trade later (if that's even possible) or if I simply discard it since I am already an elf.

Does anyone know the ruling on that?
