According to Jillian, nothing further happened between them.
Valerie's date for the Med Ball was Lucas, her soon-to-be-ex-husband.

Dev went upstairs to sleep in Harry's bed.
Jillian soon found Valerie outside of Noto's, in the company of Harry—with whom Jillian was in a sexual relationship.
After Cuba, she broke up with her boyfriend and entered into a casual, friends-with-benefits arrangement with Harry.
