Jasper is the oldest son of the beta and his mate Juneau. He is much more serious than his more laid back brother and more focused on doing all that he can for the pack. He is currently next inline to become beta so he feels like he has to work extra hard to prove that he's capable of taking up the spot if anything were to happen to his father. He is close with Benji and Maxwell, regarding them as his closest friends. He doesn't get along well with Comet, since Comet doesn't get along with his father and so he sees him as insubordinate to the pack and wishes Shade would do something about him.
Eventually he felt he needed to settle down and create a family of his own. Spotting the tension between his father and Sapphire the newcomer he initially didnt even think of giving her a chance.. Especially since he knew Scout had his eye on her. And Scout had already had the gal he had a crush on taken once before by Comet. But he couldn't resist Sapphire's charms and eventually he became smitten with her and made her his mate. He is friendly with her daughters not realizing they are actually his half siblings and he tries his best to be a good father figure to them.
