Story is the player wakes up in a random room and immediately finds a wanted poster (in black and white) of their face and a bounty. Sure enough moments later a bounty hunter arrives at the door but he isn’t the brightest.
Bounty hunter: found you. Time to get my bounty for your pretty head
Player OC: I roll to convince him that’s not me on the poster. Rolls a +5 (pretty much the best thing you could get)
Player: see here that can’t be me, the woman in that drawing is blonde
DM: The bounty hunter then proceeds to look long and hard at the pencil drawing of you, it’s still definitely black and white. or is it? The bounty hunter apologises and walks off.
