Jo Taylor and Freight Train debut in this episode; however, Freight Train was mentioned in Big Time Mansion and did have a very small appearance in a flashback in that episode.
The "Magic Middle School" script that Jo holds up shows that it was written by Scott Fellows, who is the creator of Big Time Rush.
In the scene where Bitters informs Kendall, Logan and Carlos that Jo left the pool area and returns later, money suddenly appears on his desk as the boys are leaving but in the pervious scenes, there wasn't any money on his desk as he was talking to BTR.
Camille kisses Logan, and the boys say One Tree Hill. She says "Yeah let's go with that," implying she likes him.
This episode shows James has a fear of needles.
