"Crap..." Bucky looks serious, eyebrows furrowed like he's playing Operation down there. Which is probably not good if he's trying to get Zemo to relax. Trying to slip his arm between the driver's seat and the door, he almost gets stuck retrieving the water bottle, but he manages to free himself without breaking the car with a firm yank.

Tipping some water out onto another fistful of tissues, Bucky cleans up with a wet pass followed by a final dry pass. Only then does he allow himself to relax a bit, hanging partially off the edge of the seat hovering over Zemo kissing him gently.

"We can. Still watch some of the movie. If you want..." He tugs on the throw and moves to cover Zemo with it partially, hoping they can figure out the clothes later before they need to head off. The only missed the first bit but it's probably some kind of slow intro or a convoluted plot point that will work out to be not really that important in the end.
