Robby avoiding Dennis throughout his whole pregnancy and wanting nothing to do with the child because of his own insecurities
So Dennis starts inviting Jack to his appointments instead of Robby
As time goes on towards the end of the pregnancy, Robby isn’t even involved only jack is
It gets to the point where everybody thinks Jack is the father instead of Robby
They began betting if Robby is a cuck, infertile and let Jack get Dennis pregnant and is regretting it, or found out Dennis was cheating on him with Jack so that’s why he wants nothing to do with the child
Dennis feeling petty and letting Jack put his name on the birth certificate
Dennis breaks up with Robby the next day and gets engaged to Jack the same day
