So now he is gone, he gave up his silent partner....
I had convinced myself that was Raines........but the more I think about it, is it really Kate? She was a bit into Eduardo, maybe knew what he was up to, so when Daddy went to prison, sidled up to Dario & made a deal. Would explain why she is constantly pressuring Gabi to go after Chad (so Dario can have free way to Abby), why she wormed her way into becoming CEO of DiMera by wedding the nefarious Andre.
Chad is distracted, Kate has had free rein......hmmmmm???
