IQuit iCarly - S3-E8
Continuity mistake: Carly, Sam, Fleck and Dave are sitting at one table at the Groovy Smoothy sipping a new smoothy flavor with T-Bo standing next to them. Suddenly the smoothy gets too spicy so all four go to another table and gulp down other people's waters then sit back down. The waiter places two glasses in front of Dave and Fleck. The waiter starts to pass behind T-Bo with 2 more glasses of water, but the shot immediately cuts to Sam and Carly drinking water.
Continuity mistake: When Sam, Carly, and Ernie the dance coach are backstage hearing about the talent competition, his hands and clipboard move position from shot to shot.
Continuity mistake: After Gibby is kicked into the stack of boxes, he slumps to the floor and a large sleeping bag or pillow appears beside him only to disappear in the following scene. Then when he takes off his shirt, a yellow extension cord appears on top of the boxes.
Continuity mistake: When Freddie wrestles Carly to the floor, there are three shots of her lying on the floor as they argue. The first two show her head in the same spot on the floor; the third shows her head in an entirely different spot (look at the floorboards).
Continuity mistake: An unconscious Nora falls to the floor, her head landing squarely in the center of a white tile. But in the subsequent closeup, her head is on a grey tile.
Continuity mistake: When Ginger Fox and her manager are in her room, Ginger squats down to tell her rabbit to roll over. Her bra strap has slipped off her shoulder. When the camera pans out, her bra strap is up. The camera zooms back in to her face, and her bra strap is down again.
Chosen answer: I don't know how to answer the first question but for your second question, there is going to be an episode after iPWV, called IDate Sam & Freddie which will deal with their kiss from iOMG. IParty with Victorious will not be related to IDate Sam & Freddie.
The I date Sam and Freddie proves that they are a couple.
