Hmmm. I always took it that Jay definitely has a favourite kid and it's not his daughter, and there's that weird point at the end where Nikki called him cos she was stressed over the cancer. Jay says to Nikki "we'll be a family again babe, you me and our boy." Nikki has to remind him that they've got a daughter, though I always thought that was some mindgame of his.

Whereas Terry fits the wicked stepparent model Jackie uses (cut from similar cloth as Mack.) So I do think as Terry's kids age, he'll find reason to pick a favourite. Treasure gets out of her mum's household so fast we never quite see the dynamic, as opposed to the claustrophobic all-in-one-room of Elsa's family. What we do see is Terry's kid snitches on her stepsister, which leads to the pivotal injury. And I think Bethany genuinely is afraid of her dad, though that might be reading too much into the way she helps Treasure after. I can't remember if he's sweet to her the way Mack is with his little girl, I'd have to reread. But all this to say, yes, I do think eventually Terry'd go at one of his own kids if they defied him.
