No, Blake does not represent a threat anymore. Britney's safe at #11. Her difference with DeRulo is significant and he's not increasing as much as Britney.
I don't care for the HIR outfit, it should be something as loud and colorful as the dancers!!
If her dancers have a colorful outfit, she must have a neutral outfit. This is always thought out, the main singer/attraction must always outstand among the the extras... That's how it works in every concert...
