You're right, I went back and read again and I misread some of the indictment. It says that CS-1 is a made member of the Philadelphia LCN who worked for INDIVIDUAL-2 (a capo in the Philadelphia LCN), who is also referred to as "the kid" by Servidio in the wiretaps. I knew Servidio was part of North Jersey, but I read the indictment wrong and thought it originally said that CS-1's captain was from North Jersey.

"The kid" has to be in reference to Dom Grande.. who else would be a captain "significantly younger" than a 58 year old? Either way, at this point we don't know for sure who this alleged captain is or who would be the made guys in this particular crew to know who the informant could be.
