Cut to Jack, creepily spying on everything from an upstairs window. We get a Jack voice-over as the bickering downstairs continues. "Do you ever look at your family and wonder who they are? Those are my parents. At least, they used to be."
Cut to Ron Silver carrying a bag of groceries into the kitchen. Everything is yellow and kind of out of focus here. It doesn't become clear until several scenes later, but this is a flashback, shown in Jack-vision. And if Jack sees everything in that yellowish tint, he needs to see a doctor. I think he might be jaundiced. We hear Jack's voice, haltingly: "Are we going to the movies?" In fact, let's just assume for the rest of the movie that everything Jack says, he says haltingly, with all kinds of little pauses in each sentence. The kid needs some assertiveness training. Ron responds, "I have to move some stuff." Jack: "But it's Saturday [pause] and we always [pause] go to the movies on Saturday." Ron walks into the bedroom, where he starts shoving clothes into a trash bag. Ron reenters the kitchen and speaks to Stockard, who has just lit up a cigarette: "Jack wants to go to the movies. I thought I'd drop off this stuff and maybe take him." But that won't fly with Stockard: "You're not taking him anywhere." Ron: "You're acting extreme, [Stockard]." Stockard: "Don't tell me how I'm acting." Jack again asks if they're going to the movies. Ron tells him no, and when Jack asks why, Stockard tells him, "Because I say so." So Jack again points out they always go to the movies on Saturday. You know, we're seeing this scene through Jack's eyes, so it's not like he didn't hear all the previous dialogue. I think the kid is a little slow. Jack voice-over: "To be honest, I didn't give a damn about the movie, but there was something going on and I didn't know what it was, and I didn't know what to do except act normal." That clinches it -- the kid is slow. Still in flashback, Stockard throws her cigarette butt into the sink and chokes back some tears.
We leave jaundice-cam behind and return to the present (a.k.a. 1982). Jack is still creepily spying on his parents from the upstairs window. Ron hikes up his tool belt and leaves.
It's night. We see a pyjama-clad Jack leave the house and approach the new basketball hoop. V.O.: "It's like you had a hero, and all of a sudden he's gone. When you're a kid and you've got a father who reminds you of Superman [wait, this is still Ron Silver we're talking about, right?], who seems like he can do anything -- a father who's the kind of guy who climbs up on the roof to rescue your dweeby G.I. Joe when it's caught up there in some idiotic experiment -- and then one day he's gone, disappeared into a million different green plastic garbage bags, with no explanations offered, nothing anyone says later makes a bit of difference." Through this entire speech, Jack is aggressively headbutting the pole that holds up the hoop, until it's knocked about 10 degrees off the vertical. Damn. No wonder the kid is slow. Get him a helmet.
