Silas is in his room, loading up his knapsack with the usual teenage accessories: bong, condoms, candles (scented and votive). He pulls open his drawer to grab his lighter, but of course it's not there. Silas goes into the kitchen -- where Shane is reading an anti-depressant pamphlet -- and asks Lupita if she's seen the lighter. Shane timidly says it got confiscated and is now in the principal's office. Silas looks for a second like he's going to cry, then calls Shane a "fucking idiot." Shane instantly fires back, "You're an idiot -- fuck you!" "That was Dad's lighter!" Silas screams, and -- just as Nancy walks in the door -- he punches Shane square in the face. Shane goes down like a sack of potatoes and starts crying, and Silas, running on the fumes of how own anger, keep repeating that Dad gave it to him. Nancy shoves Silas aside to get to Shane, as Silas looks on, shocked that he just did that. Silas then runs out the front door as Nancy curses him under her breath. Dude, you forgot your bong and condoms!
Later, Nancy drives past Megan's house and sees Silas in the living room, explaining things to her parents who, in turn, place comforting hands on his shoulder. Nancy looks incredibly guilty but, of course, Megan's parents have the luxury of not being Shane's parents (they're not Silas's parents either, but you see what I mean), so it's not like Nancy would be in a position to offer Silas this kind of support, even if she wasn't so busy selling weed and running a sham bakery.
By the time Nancy gets home, it's dark, which means she doesn't spot a bruised and bloodied Rent-A-Cop until she's almost to her door. He scares the shit out of her by just being there, but he's not there to threaten her or shake her down. In fact, he's got her stash in a duffel bag and gives it back. Rent-A-Cop actually takes his hat off before he apologizes, telling Nancy he didn't realize who she was. He doesn't specify what brought about his change of heart -- or his busted nose for that matter -- but he says he's now at Nancy's service should she need anything on campus. Nancy's still freaked and says what she needs is for him to go away, now. After he does, Nancy checks on her returned weed and wonders who her fairy god-person was this time.
