I have no idea what the heck is the matter with the writers, having that kind of dialogue. Of course John & Marlena raised Brady & Belle together.
But just to correct something, when Brady was 19 and came home from college he WAS very definitely very angry with Marlena, and it took a while for him to say why. Seems the family photos that adorned the piano in the apartment did not have a framed photo of HIS mother, Isabella. Honestly, it was very stupid reason back then, but he said he felt they did not want to remember her. Of course he never had mentioned it, just was mad. And Marlena put the framed photo of Isabella on the piano, and all was well thereafter.
I guess, Brady spouting off like that at his father, is a result of writers not doing their research properly, and Eric Martsolf being a replacement Brady.
I don't see how Brady can fault John for being in a hospital in Switzerland for a couple of years, Brady was all grown then. Does he mean that it was Victor who rescued him in Vienna and put him in rehab.......not John? Am clueless. Brady was all gung ho with John after those pension funds disappeared and John was starting up Basic Black anew. ????
