Lab Rats - Which Father Knows Best - Clip

Which Father Knows Best?” is the 11th episode in Season 3 of Lab Rats. It first aired on July 7, 2014.[1] This is the 56th episode overall.


When Donald fails at rebuilding Bree's bionic chip, Leo recruits Douglas behind Donald's back and they have to work together to repair Bree's bionic chip.


As Donald attempts to repair Bree's damaged chip, the replacement chip keeps malfunctioning, much to Donald's frustration. Though 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 is seems to work, it also malfunctions by causing Bree to run uncontrollably. The three manage to keep her still, the Davenports' 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 (since her heart would've exploded from the strain of her uncontrollable speed). Meanwhile, Adam and Chase try to find a way to replace Bree's speed. While Chase manages to power up Davenport's motorcycle to go 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, who accepts.
