Jasper in that day, he was really happy, when it seemed in the near future, he and Stella, seemed to be able to breathe a sigh of relief. Because Dexter doesn't seem to be bothering them at this point. Because he was sure that it looked like Dexter might have other things to do, which he would take care of. And also he wouldn't be chasing after her, nor Stella either, at that time.
Actually, Jasper knew that he and Stella were people who really needed time to have fun, because sometimes he was too bored to just stay at home when the holidays came.
For some reason Jasper really felt sure that Dexter Franklin would not disturb him and his family in the near future. Because he usually feels anxious, and not calm, when he goes to work to his office. But at that time, in fact, he felt so at ease, because it seemed that no one was watching where he was going.
