When Sikowitz drops the piece of paper before he runs out of the classroom, he drops it at the front of the stage, but when Jade goes to pick it up, it is at the back of the stage.
When Jade scrunches the piece of paper and throws it, it lands on Tori's right side, but Tori picks it up on her left side.
Right when the curtains are closing, Tori is horizontally passed out on the ground. In the next shot, when Cat and Lane rush over to help her, Tori is on her knees with Andre helping her keep vertically balanced.
Tori said that Robbie was wearing SpongeBob underwear, but Robbie's underwear can clearly be seen to not have SpongeBob on it.
Tori ends up donating 3 pints of blood for Robbie's operation. No hospital would take more than a pint of blood from a donor within an 8 week period.
On Beck's Profile on TheSlap.com, Jade comments on his last post that he will miss the play that will be on Saturday, but in this episode, it states that the play will be on Friday.
It is likely a second show was added.
Tori and Jade didn't really need to fight over the role in the first place; they could literally just switch places for both opening night and the succeeding show after that, since Tori's the lead and Jade's her understudy. Although this could be a problem if either of them are selfish about doing the role.
It is not safe to get three pints of blood taken in one day (a person who gave blood must wait eight weeks before giving more), especially for a small body build like Tori.
The hospital could easily get sued for this action, considering how it made Tori very dizzy and she passed out during the play.
The hospital could be sued or even shut down for irresponsibility and most of the doctors and nurses could lose their jobs.
Tori invited her friends to eat sushi with her at Nozu, but Nozu didn't even exist (or rather was not known by them) until Season 3.
