Man I don't think that was Chase's intention. He already had trauma and didn't want to sleep with anyone and hated pheromones. He went into rut and Josh allowed the sex to happen he wasn't coerced and both were slightly out of their minds, Chase more than Josh, hence why Chase had zero memory but Josh remembered everything and made peace with it. Calling it baby trapping is a bit much...
That Chase didn't want to sleep with anyone has nothing to do with trauma, it was more a principle of his that he didn't want to have sex without feelings. The meds he took had side effects, which lead to this problems with omega pheromones.
The problem with Chase is, that he let his pheromones build up instead of releasing them with someone or getting an injection at the hospital on his own.
It wasn't intentional, but the situation with Josh would have never happened, if Chase took his pheromone management seriously.
And well, Josh trapped himself, he went to the clinic too late, when abortion was already out of the question.

So many people getting Dane wrong it's astonishing. When was any mentioned he hate having kids or kids? He's literally the one starts thinking about it first after he gets together with Grayson. He avoid them because of his trauma.
Also kudos to Grayson that actually trying to communicate instead of letting it fester and come up with a misunderstanding on his own. Is it going to go well? No but it's way better to ask it and be done with it.
