**The brother relationship between Leo Dooley and Chase Davenport** is one of the main relationships on *Lab Rats.* They are brothers, best friends and teammates, but there are times when the brothers are in conflict with each other (*Lab Rats: On the Edge*). Though they tease each other, Leo and Chase look out for each other and are extremely close, sometimes bonding with each other more than their relationships with Bree and Adam.

## Key Moments

* **Crush, Chop and Burn,** Leo and Chase meet each other, approximately in 2012,  when Leo accidentally stumbled across a secret elevator and found a lab within his step-father's basement. Chase was the first bionic teenager Leo had seen and was scared of his unknown step-siblings. However, Leo grew more relaxed when Donald explained who the three siblings were and admittedly, both Leo and Tasha were disturbed by how Donald treated the kids, such as making them eat fiber pellets that fell from the top of their capsules into their arms. When Chase first met Leo, he could barely stand him but  quickly warmed up to Leo when he took them to school and showed Chase (and Adam and Bree) the outside world for the first time. Leo establishes that Chase, Adam and Bree as his best friends and was sadden to see them gone when Davenport was going to send them to Facility X in the Frozen tundra. Chase called Leo the first friend they ever had (with Adam correcting them that Leo was their only friend. Leo admitted that in their short time together, he came to love them, which Leo unknowingly admitted to  the Lab Rats when Leo thought they just robots at the time. Later, when Davenport and Tasha toldd Leo taht they sent the "robots" to a recycling department and went to rescue them. Chase was immediately concerned when he first saw Leo fall into the recycling bin and sprung into action to save his stepbrother, along with their other siblings. After seeing the kids use their bionics, Donald decided that the kids could stay and Leo was overjoyed.
* In "Leo's Jam," Later, Chase and Leo fall in love with the same girl, aloong with Adam. Despite winning Danielle, Leo chooses to apologize to Adam and Chase for sabotaging their chances with Danielle and calls them his brothers. Chase later acknowledges Leo as his brother in "Exoskeleton vs. Grandma," where Chase and Leo apologize to each other

* In "On the Edge,"when Leo discovers a new ability called EMP generation with Taylor, Chase forbade Leo from ever using the ability because it proved to be too dangerous to use. However, the two disobeyed Chase, and used the ability again; however, the EMP generation resulted in Leo permanently blinding Taylor. The older Davenport brother scolded Leo for causing her danger and deems him unworthy of being a leader. Leo takes his brother's words at heart, especially after learning Taylor will never see again, and decides to quit the team and the academy and move back to Mission Creek. Chase never meant for Leo to quit, possibly thinking he had been a little harsh on his brother, and he felt that Leo should stand with them during the award ceremony because he was a hero just like them. Later, Chase and their family are trapped on the Hurst Bridge and Leo goes to rescue them. On the mission, Leo refuses to give up on saving Chase, who tells his younger brother to let go or the car will take him too; Leo refuses and saves his brother from falling and the two brothers hug each other, glad the other is safe from harm and finally reconciling. Afterwards, Leo is able to stand next to his siblings and later, Chase congratulates his brother to finally making it, claiming he couldn't be any more prouder than him.
