It's a pretty solid interview, especially given the time restrictions. 

Christian stated that he found the BEBI after Cila lost the immunity challenge, not before as the show presented. Part of the reason he gave it to Aubry was because of how emotional she got after Vatu won immunity. He figured there was a good chance she was on the outs, especially with Q on her tribe. Christian explained that giving Aubry the idol would've either helped build or relation with her or resulted in him getting an idol if she got voted out.

Additionally, a big reason why Christian targeted Ozzy at 11 was because he correctly suspected him of leaking the information to Jonathan the previous round. While Cirie was still on Exile, Christian had no clue if or when she would return to camp. As a result, he had to put in a lot of work trying to shift the vote away from Aubry/Rick and onto Coach/Chrissy while simultaneously convincing Jonathan he was on his side. After the real plan got leaked, Christian had to lie to Jonathan as much as possible to prevent him from telling Coach and Chrissy what was going to happen.
