Not much is new with Jack and Bradbury- Jack still thinks City Hall could have much worse as its head of security and likes and respects Rick well enough as a generally solid dude. All their interactions so far have been positive and Jack values that potential connection within City Hall. Rick isn't really 'in' with Jack yet though, which means Jack is still fully prepared to snap his neck if he turns out to be a terrorist mole.

Yako is another story. She keeps surprising Jack! She demonstrated an uncanny ability to read him during the research log which he both hates and is impressed by, and his mind is just blown that she singlehandedly made it possible to resolve a terrorist crisis- that's what he usually does! So Jack's respect for Yako's abilities is much higher than it once was, but she's still that girl who helped Danger braintorture him in the VR session and it'll take a while for Jack to get past that.
