On one hand Gjert is saying that he wouldn't choose to do this (coaching) again if he would know that things end up like this. (Disclaimer: this interview was released today but it was recorded before Jakob's wedding, which he wasn't invited to).
On the other hand, Gjert is coaching another 1500m runner with the goal of achieving a gold medal over his own son, and also hired a lawyer to supposedly fight against the federation (who we assume are doing what Jakob has requested or feels most comfortable with).
It seems like the reconciliation or apology that Gjert is considering don't align with his current actions. Henrik, Gjert, and Tone addressed this topic on the show, that Gjert cannot be both coach and father. They've known this for a while, but now it seems to have really come to a head. We don't know if the rift was caused by little irritations that escalated, different ideas about training, frustration with such an anxious and overbearing coach, or something more sinister. What we do see, unfortunately, is a fractured family, probably experiencing a lot of pain from this. No matter what, the situation is sh!tty for all of them, especially as it plays out in Public.
