It took me an entire season to realise that this is a love triangle. I avoid them like the plague, but somehow this one is palatable.
Time for my controversial take.
The "chemistry" that a lot of people see between Ian and TJ is simply just obsession and addiction. Ian wants out of the chains TJ has held him in, but I guarantee if TJ somehow miraculously let go of them, Ian would sit still like a dog awaiting a command. They're both bad for each other, but TJ is too consumed to either realise or accept it.
Jo and Ian were doomed from the start. There is little hope of them ending up happy together. Ian is tied to TJ, and no matter how far Ian runs, he'll always have a line leading directly to him. Jo is being pitted against someone on a much higher level than him in terms of emotional fondness. No matter how much Ian may want him, a part of him still belongs to TJ.
Jo offers him stability but TJ offers him familiarity.
My prediction and wish is that Ian doesn't end up with either. He wouldn't be happy with TJ and it would just be so unfair to Jo. Gaining his freedom and starting a new life would be the best option for him. He's never been alone for long enough to establish himself as an individual. Give him a few years to figure his stuff out, then he can try again.
