"Jimmy" starts off with Virgil having a flashback to Richie being hurt when at a session with the psychologist Dr. Franklin due to recent events that he explains to her as the episode's framing device.
Virgil and Richie end up interacting with the titular Jimmy, who gets regularly bullied by Nick Connor and his friends. To Dr. Franklin, Virgil vents a bit about how a teacher pays attention to latecomers (like him due to an encounter with Carmen Dillo[presumably not saying why he was late to Dr. Franklin]) but she was oblivious to the bullying, acknowledging that he didn't bring it to her attention either.
Virgil ends up bringing Jimmy an unused mouse of Sharon's to replace the one the bullies broke.
Jimmy's mom is pleased that he has friends over, although she also 'asks' him to not scare them away, which seems to frame the situation as due to something lacking in Jimmy. On the one hand, his mother framing it as his 'fault' that he doesn't have friends cannot be helping Jimmy's mental health. On the other, this is sadly foreshadowing.
At first, things go well, with Jimmy talking about his nerdy interests. Then he brings up how he can access his dad's gun, which greatly upsets Virgil as his mom died due to gun violence. While Virgil's reaction is particularly acute, I do think a first visit is way too soon to loop classmates/friends into illicitly seeing/using a parent's belonging, regardless of what it is, but particularly when it's something as dangerous as a firearm.
He storms off, getting Richie to go with him.
In Dr. Franklin's office, Virgil wonders if he could have handled the situation better, thinking he was a "chicken" about it, but the psychologist reassures him that leaving was the smart choice given the dangers of guns.
Virgil and Richie did continue to interact with Jimmy after his offscreen apology, and next Saturday's post will go into about the Fright Fest situation.
