my favorite moments are when he just absentmindedly agrees with daria against helen without realizing there's an argument or even hearing daria's side.
then he gets tons of shit for it
honestly if i could change one thing about the show it would be daria sticking up for her dad more. showing some appreciation. helen i can see her snubbing, among other things she knows she can take it, and she gives more attention to quinn anyway, but jake did little if anything wrong.
i guess there was some lingering resentment over what she thought was him basically trying to escape the stress of having her as a kid. and didnt find out otherwise til the end
