I had a little more time than normal this morning, so I took the boys for a nice long car ride- about an hour and fifteen minutes this time. They cuddled almost the entire time. Swatch really cuddles up to Rolex's bum when he's scared. Then when we got home I set up the pen on the landing again. They were good together for a solid fifteen minutes. Swatch immediately dominates the litter box. Rolex shared it with him for a bit and then explored the rest of the pen and cuddled up next to me for a bit. They put their heads together ("groom me") behavior a few times without any aggression, but also without anyone caving a grooming the other bun.
