Yes , he asked Malcom "Who do you ride with these days?" but he could have asked that even if he never met him in person before. It is quite a discussion , and it would be fair to make a poll , where fans could vote , if you went with that story. "Did Ben meet Malcolm for the first time in the Kickstand, were they friends before that?" I remember Ben's face wasn't so happy when Malcolm entered the Kickstand. I would believe that Ben didn't know that the old man was Malcolm Corley himself. Again , it is your game. I just said my opinion
I could help with the story , as i'm currently writing a fan-novel , not with Ben as the main protagonist though. We could merge the two worlds , my novel and your story , and create something special.
