It said that she and Kaz made it out Mission Command alive. It also turned out that Oliver survived as well. Overjoyed, Bree went back to Centium City with Chase and reunited the team.
The next day, Bree got a peculiar Mission Alert saying that something was going on in the Pyramids in Memphis, Egypt. Bree and Chase went to Egypt, and were very suprised to see a Pharoah emerging from the Great Pyramid of Khufu. After incapacitating the Pharoah, Bree went to the bionic academy to get Leo to extract the Phroah's powers. After that, Bree and Chase checked out the pyramids while they were in Egypt, and Leo went back to the acadmy with the pharaoh.
Two hours later in Centium City, Bree was delighted to see Adam geo leap in the penthouse. He said that Leo wanted to tell her that the pharoah she and Chase fought was probably a "bad guy". When they tried going into Mission Command to see what was going on, they were locked out. They went to the Lab in Los Angeles to see who was in there. Much to Bree's shock she found Roman in Mission Command. She says reieved to see Olivrer there defeating Roman, but there was still unanswered questions.
Bree rushed to the academy and brought the pharaoh to the Lab to be interrogated by Adam. It was revealed that Bree and Chase never defeated Roman and Riker in Holiday Park, just the androids in their place, and that the pharaoh wads actually Riker the whole time trying to distract Bree and Chase. It also turned out that Roman and Riker were working for Rodissius, and got his powers back via the Arcturion Space Rock. When Riker was taken out, Bree and Adam hurried to Holiday Park, and swiftly defeatd Rodissius.
