A man intercepts Tilly as she arrives home from work at Deniston Pharmaceuticals, warning her that she has been exposed to a dangerous toxin. He tells her she must wait for the decontamination truck to arrive so that she can be checked over. Tilly says she needs to go inside the house to use the bathroom, but the man tells her no, that she would only spread the contamination inside the house which would require them to turn the place upside-down. As things stand, if she has been exposed her car will have to be dismantled and sterilized. So, Tilly waits, growing restless because she badly needs to pee now. She is told the trunk should arrive in the next ten minutes, but when those ten minutes have been and gone and there is still no sign of the truck, Tilly grows both restless and irritable. She's bursting and can no longer hide her problem. To her mortification, she loses control of her bladder just a minute before the truck arrives, so that when it does show up she is standing there in pee-soaked jeans. Too embarrassed to stick around, Tilly runs off around the back of the house.

Later in the day, Tilly turns up at the Decon Unit, intending to complain about the way she was treated, only to find herself placed in a sealed room to await the man in charge. Tilly can't believe her bad luck when, after waiting for an extended period, she finds herself desperate to pee again. She would pull up her skirt and squat down on the floor, but she knows someone is watching her through the security camera mounted in the corner of the room. Tilly speaks to the person on the other side of it, telling him (or perhaps her) that she needs someone to come and let her out right away, that it is a matter of urgency. No one comes and Tilly again finds herself in a highly embarrassing predicament. She concentrates hard and does her best to wait for the arrival of the man in charge, but she runs out of time and wets herself again, the pee streaming down the back of her skirt and onto the floor. When she has finished, she stands up and walks around the room's only seat, then looks up and the camera and says, "I'm sorry."
