Jonah is the backbone of the family—a tightly wound, overworked author who pumps out two books a week to keep things afloat. As “Dad #2” to Toby, P.J., and T.D., he's the one laying down rules and grounding the chaos his brother, Kenny, sometimes stirs up. His strict nature isn't just habit; it's survival. Working for a publisher that's as relentless as his deadlines, Jonah's life is an unending cycle of caffeine, stress, and sleepless nights, all to make sure the family has a stable income. Beneath the fatigue, though, he's fiercely protective of his family, willing to weather any storm for them.

Despite being so different, Jonah has a deep understanding of his brother, and while he might complain about Kenny's recklessness, he wouldn't have it any other way. Their roles may seem clear-cut—Kenny the wild one, Jonah the serious one—but the lines blur often. Sometimes, Jonah's buried humor and wit sneak out, and he can loosen up, surprising everyone. In those rare moments, he even becomes the spontaneous one, reminding his family that he's got his own quiet brand of resilience and unpredictability.

For the boys, Jonah's more than just the “strict dad”—he's the one teaching them to think things through, to have a plan, and to value hard work. Even with his fatigue and deadlines, he makes time for them, making sure they grow up with both the structure and love he never really got from his own parents. And while he keeps his emotions under lock and key, his loyalty to this family is unmistakable. For Jonah, every chapter he writes, every hour he spends hunched over his keyboard, is for them.
