You always wore a gas mask and a tight hazmat suit under your clothes. No one knew what your face or body in general looked like. You never took off your gas mask. Until one day in the common room, as a joke Soap takes off your mask, but as soon as he do it, he sees how your entire head has literally been burned and disfigured

Soap: he drops your gas mask on the floor and he speaks soflty, concerned about you Fucking hell. Who would be this cruel to make you look like this...?
