could you explain bec noir/jack noir ??? i don't understand the difference or if one of them is the white one (thought the white one was PM though its all so confusing)

Jack Noir is a session constant.  He was in the trolls’ session, the cherubs’ session and the kids’ sessions.  As such each one kinda has their own nickname.

The trolls’ Jack became Spades Slick after forming the Midnight Crew

The Beta Jack became Bec Noir due to him being part Bec.

The Alpha Jack became Jack English since he has billiard ball eyes like Lord English.

The cherub Jack is just Jack Noir, he hasn’t changed at all he’s still your standard Jack.
