Jasper had indeed found the showers and had managed to wash away all the zombie blood from his suit and hair.  The suit itself had been designed to dry very quickly so it was only a matter of drying and combing out his long hair before he rejoined the group in making the last adjustments on their new transport.  Jasper had seen Cole talking to Kay and even though he and Kay really didn't have anything going together Jasper could not help but feel jealous and a bit angry at Cole for moving in on the woman he had been hoping to get to know.  Sure the other women agents on the team were all beautiful as well but there was something about Kay that Jasper felt more of kinship with than the rest.  Probably because both of their powers were very similar in the way they were used and the amount of destruction that could be caused with them might have been part of it.  If it did turn out that Kay chose Cole then Jasper would worry about finding another but he didn't simply plan to roll over and let Cole win.
