Percy developed an infatuation for Vex early on in their relationship, but had kept it to himself and buried his feelings deep down because he never considered them being together to be "healthy". From time to time, Percy was eager to create custom ammunition for Vex, Hawkeye-style, such as when he made her a grappling hook arrow and three exploding arrows. The results of the tinkering earned him a kiss from the ranger. It was ever since his first gift to her that Vex started having feelings for the gunslinger but, like Percy, kept those feelings buried within her.
