Continuity mistake: When young Shakes is running away from the hot dog vendor, he has the hot dogs in his hand and doesn't toss it away before he meet up with his friends, yet there is a shot in between where we can see him running with empty hands. (00:22:40)
Continuity mistake: The last time Shakes serves as an altar boy for Father Bobby, he puts the white coat on top of the black gown, and it is all straight. Yet, when he turns to Father Bobby, the coat is lopsided and hangs over his left shoulder, and Father Bobby straightens it again. Even if the coat slides a little when Shakes leans towards the mirror right before turning to Father Bobby, it wouldn't pass his shoulder unless he did it on purpose. (00:28:20)
Continuity mistake: On the subway, the background is shifting as we see through the window when Michael is in focus. Yet, these shots are inter-cut with shots focusing on Carol. In some of these shots, the background is all the same. (01:41:50)
Continuity mistake: When Michael and Carol are talking on the subway, Michael reaches out and begins touching/stroking Carol's hair. But in the reverse shots of her, his arm and hand, which should be visible over her shoulder, are nowhere to be seen.
Continuity mistake: In the scene where the boys are ordered to eat of the floor, before they go down the food is very spread out. But once they are down and picking from the food it is in much bigger piles.
Answer: I believe you are confusing two characters and what person's sister. The girl in the wheelchair (can't remember her name offhand) was Hector Maldonado's sister. Hector was on the opposing stickball team. Carol (who was not in a wheelchair) was Michael's girlfriend, so Shakes saw her as "taken" and "off limits." (Shakes wouldn't steal his friend's girlfriend).
