I am not convinced God will come in to the story. The big suggestion is tackling homophobia and drug, the first interactions all related to

husband and wedding band, another gay prisoner, his cell mates Lesbian best friend and all of this smacks of Jason sussing

is gay and

was his partner. With this and the Gordon being his dad

will be open to verbal and physical abuse which will in turn tempt him to find a release (drugs). Pretty dark and heavy stuff but if the suggestions are that he will be out April time then we don't have to suffer it too long.
Ian did say the Robron separation would make them stronger.
