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.
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.
