No, the DR didn't allude to Dani's actions.

It was a conclusion Brendon came to on Friday night.

Watch the flashback if you can. When he and rachel were taking a bath he put it all together and then that night he told rachel he wanted to talk to jeff and jordan the next morning to see if they were all on the same page.

After that Danielle went up there and right out said they needed to backdoor Jeff. That's when BR knew for sure Danielle was against them.
