Here’s what I see...
JS is in a hotel, snowbound. Long day on the set.
Not sure whether they will shoot in the morning so he decides to get some laundry done. Whites first.
He heads down to the laundry with a box of tide. Stops at the front desk to get some bleach. Slips and falls in the laundry room, spilling the bleach on himself and bruising up a little bit.
The rest is Hollywood magic.
LOL! Perfect script! Ive also seen that the area of Chicago he was in is known as boys town.
The name rings a bell but the messenger never delivered.
