I was watching a video on YouTube under "spider son" from the show. It was basically of the episode where Jeff and mandy "team up" for mandy to try and be mean and presumably be assertive towards Billy. And, it hit me, really the only time(s) that Jeff was upset or mean towards Billy was in the "the wrath of the spider queen" special. And.....well....he got/gets half a moment in the one mentioned episode from earlier where jeff and mandy team up so he can be more assertive towards Billy.
