Sink or Swim (2) (S03E02)

Leo and Donald manage to break free from the elevator. Principal Perry allows them to stay at school temporarily, hoping to get her money from Donald faster. Meanwhile, the Lab Rats sneak onto a cargo ship to evade the FBI, facing a tough decision: stay silent or help avert a submarine collision that could expose them. They choose to intervene, but when Chase activates his GPS, it reveals their location. Douglas, disguised as Donald, captures them and discloses that his new bionic ally is billionaire Victor Krane, who plans to eliminate the Lab Rats. After Donald informs them that Principal Perry is keeping their secret, they head home, only to be driven mad by the Triton App and attack their family. Leo manages to disable Chase's app with a heartfelt conversation, and Chase helps shut down Adam and Bree's apps. Later, the Lab Rats and their family are devastated to see the destruction of the lab.
