Well the theory of this
if it has merit goes like this.
Jim intends for there to be similarities between Marcone and Cable.
Jim names Marcone in some way after Cable, hence Marcone's first name is Nathan.
Marcone has connections to Summer and Winter, perhaps going so far as to his last name too.
This gets me to wondering if perhaps Allison Ann Summers in Grave Peril is Marcone's daughter. In my theories this would mean Harry just saved his granddaughter. Cool, huh Aside cont. Priscellie points this out on Reddit years ago about Allison Ann Summers:
Alison Ann Summers (the baby Harry and Michael save from Agatha Hagglethorne in GP) = Alyson Hannigan and Buffy Anne SummersJim tells Priscellie Marcone's first name after she asks about it. It seems it was told to her only, not others so that would/could suggest it was information told in confidence not meant for common knowledge yet.
She mentions it. It is recorded by someone in WOJ section on Marcone. Since it leaked, there is a need to blot out this information. Therefore, it is associated with Hendricks instead of Marcone. It should be noted that Jim admits he lies for a living and has said don't believe a word he says. I think we should at least use same standards of questioning WOJ of those close to Jim when there isn't other qualifying evidence in text, comics, videos, q&a's etc.
In conclusion, this really only has merit if there is a desire on Jim's part to draw strong parallel between Marcone and Xmen's Cable, even down to their first name.
