When he starts fighting with Adam, she activates her Commando App and thinks Chase is her baby. While she destroys the bionic academy, Bree forces Chase to activate his Commando App by embarrassing him so he and Kate can battle. Unfortunately, he teams up with her. Douglas gives Bree a Commando App and she and Kate begin battling each other. Bree wins and Douglas extracts Kate's chip.
