• This is the first episode Douglas appears without Donald.
• This is Spin and Bob's first absence ever since they were introduced. (First Day of Bionic Academy)
• The Lab Rats suspected there was another rebel in the academy after the events that happened overnight.
  • It is revealed that it was Leo attacking the academy and the others. It is also revealed that he sleepwalks due to his arm glitching since he does not have a capsule. Douglas did not think Leo needed a capsule, because he isn't fully bionic.

    • It is revealed that Kerry has still not changed. She is still mean to the others.

Goofs

• In this episode, Chase's bionic hearing is shown as a passive ability. In previous episodes however, it's portrayed as an ability he has to consciously activate.  
• When Chase confronts Bree about texting during their early morning surveillance of the Academy, Chase didn't have a phone with him. After Bree sent him a text, a phone appears strapped at the right leg of his mission suit.
