The Big Bang Theory Season 12: 10 Things That Must Happen Before It Ends
7. Howard's Dad Visits Him
Ever since he was a child, Howard hasn't had the greatest of upbringings. His father deserted him when he was only 11, and his relationship with his over-bearing mother was rocky before her passing. With no-one left for him to look up to, is it time for fans to finally meet Mr. Wolowitz?
He's one of those names that gets mentioned but never actually appears in an on-screen capacity. Howard, of course, comes across as resenting his father for what he did, but there have been times where he appears to miss him. There isn't really much we currently know about the patriarch of the Wolowitz family, so there would certainly be plenty of fascinating drama to be mined if it were to happen.
It's been an ongoing storyline since the beginning of the show as well. Unless TBBT producers are out of their minds, they wouldn't end it without Howard's dad appearing at least once, whether the two of them make up or not.
