Lab Rats (2012) : 3x11

As Donald attempts to repair Bree's damaged chip, the replacement chip keeps malfunctioning, much to Donald's frustration. Although Leo believes Douglas can help since he was the original creator, Donald refuses to even see his brother again. Realizing Donald won't change his mind, Leo finds Douglas, anyway, who reluctantly agrees to help. While Donald is away, Douglas creates a new chip as close to the original as possible, and though it seems to work, it also malfunctions by causing Bree to run uncontrollably. Donald finds Leo with Douglas at the lab, but helps out and all three manage to keep Bree still; however, they still can't find a solution. After several minutes, they finally find the error and collaborate for the first time in years, fixing Bree's chip and saving her life. Meanwhile, Adam and Chase try to find a way to replace Bree's speed. While Chase manages to power up Donald's motorcycle to go 350-400 MPH, it runs out of gas almost instantly. After Bree's chip is fixed, Donald still kicks out his brother. While watching Bree apologize for her mistake, Donald realizes everyone deserves a second chance. The next morning, Donald offers his brother a chance to move in with them temporarily, and he accepts.
