Okay... lemme see

Olive Penderghast from Easy A - I've seen ONE other player with an Olive

Fire from The Graceling Series I've not seen another player with her

Duncan from Total Drama Series - I've seen ONE other player from this fandom, they played my Duncan's other half... but were uninterested in playing with me

Mallorie Cobb From Inception - never seen another one of her

So ya, those are rare bbs - I should put them on the Rare Muse Meme next time it comes around
