I really cried as Vera's coffin went through the curtains at the crematorium, mainly due to the music ! How come their other grandson, Brad is never mentioned ?? When Terry was going out with Tricia Armstrong, she had a little lad called Jamie ( who now plays Ely Dingle in Emmerdale ! ) and then she had a baby called Brad. How come they have never been mentioned ??
As very often happens with splintered families, I expect Trisha lost contact with Jack and Vera after she started her new life with Ray. It sadly happens too often in real life.
