IDK about Jack because I think the Grayson's can easily point Jack out as Victoria knows that Jack & Ashley are in cahoots and Jack was willing to team up with her to take Conrad down. So any actions taken against them they'll probably place the blame all on Jack especially now that Declan is dead. I know Emanda will protect Jack but Grayson's can be nasty and manipulative when they want to be.
Then again Victoria can be distracted if that's her son that showed up at her door, Charlotte's pregnancy, Daniel is kind of clueless. Conrad might be the only one who really doesn't have a major distraction.
Jack poorly handled his revenge by telling Victoria.
I believe he became a part of the inner circle when Helen visited him in jail.
Exactly, there was a flashback during that scene.
