IMeet Fred - S2-E10
Character mistake: Carly says Shelby, ID Is 4 hrs away. It's more like 11 and a half hours from Seattle.
Character mistake: The girl Spencer dates does not speak Uzbek, she speaks Russian.
Character mistake: Sam says that "Ginger Fox USED to be good; then she hopped onto the crazy train and ended up on has-been island," (or something of that sort). Freddie then says that "technically, you can't take a train to an island, because they are surrounded by water." This is untrue, because technically, Manhattan is also an island, and there are MANY trains that go to and from this island.
Character mistake: Freddie mentions that they had an audience of 355k which was the most they've ever got. But in the earlier episode of ISpy a Mean Teacher, they had an audience of over 500k.
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.
