The Big Bang Theory: 10 Major Predictions For Season 12
4. Howard's Dad Finally Appears
Throughout every season, Howard's father has been mentioned only by name. We've never been given the privilege of meeting Mr Wolowitz, or Mrs Wolowitz for that matter but we at least know she was around for Howard. The father of the family was never anywhere to be seen from when Howard was just a young boy.
It's a common thing brought up by Howard, with a letter even being found in his closet in one episode. Despite still feeling mad at his father for walking out when he was young, Howard never did attempt to track his father. Although he rarely showed it, Howard was content with his mother and friends around him, and didn't see a point in introducing his father into his life.
With Howard and Bernadette recently having a son, it would be a fitting way for us all to finally meet Howard's father - by having him appear and tell Howard to be a better father than he was. Granted, it wouldn't be the end of the world if we didn't get to see Howard's dad but it would be nice to finally have closure to have for the Wolowitz clan.
