These things were brought up in conversation today at roller derby practice. My subtle mutation - bilateral syndactyly. What’s yours?
With Greyson and his earlobe, I'm reminded of a thing in Fallout 2. If you take too much radiation damage you will grow an extra toe. The next time you use an auto-doc it will remove the mutated toe and put it in your inventory. Your character is very profoundly sad about this when you interact with said toe, then you get a series of options for what to do with it. One of them is to eat it, to which the game responds in horrified confusion, "YOU JUST ATE YOUR FUCKING TOE!"
