Maurice is portrayed by a hen and not a rooster. It would mean Maurice is a girl and not a boy.
It is revealed that Nora was sentenced to 5 years in prison for kidnapping the iCarly gang at her house. Her sentence would have been longer in real life. However, she might have gotten leniency because she was 16 when she first trapped them, but if she was tried as an adult for the crime, she would have gotten a longer sentence.
It is unknown where Nora's parents were since they went to jail with her in iStill Psycho. It's most likely she was in the same cell with her mother and her father is in a different prison.
It is unknown how Nevel got back to Seattle so fast. It is also unknown how he escaped the mental hospital but it is likely he waited until the guards were out of sight so he could escape unnoticed.
Nora says she wants to destroy Carly, then Sam, then Freddie. She skipped Carly because Italy is too far away, so she decides to begin with Sam, who is closer to her, in Los Angeles. However, Freddie was the closest, because he was still in Seattle.
In the Nora promo, Tandy has a black face.
Nora did not want revenge on Gibby, even though he was the reason her original plan failed. She also didn't plan to get revenge on Spencer even though he helped get her re-arrested.
It's unknown why Sam didn't call Carly to warn her about this. Maybe because since Nora thinks Italy is too far, she didn't think it was necessary. On a side note, it is unknown if Sam ever called Freddie to warn him about Nora.
It is unknown how Nora knew Sam & Cat were at Bots. She most likely asked around and showed their pictures to other people.
