The Big Bang Theory

The Convergence Convergence

Series 9 - Episode 24 The Convergence Convergence



A season that began with Penny and Leonard eloping to Las Vegas ends with TV’s unlikeliest couple preparing to marry again – this time for the benefit of family and friends. Joining Leonard’s psychiatrist mother Beverley is his anthropologist father Alfred and Sheldon’s Bible-bashing mother Mary. Fireworks ensue, but not all of them in expected ways…

There’s a respectful round of applause for Judd Hirsch (Alex in sitcom classic Taxi), making his debut as Alfred, and while the episode lacks the dramatic impact of previous season finales, it’s nice to see the writers investing in characters other than Sheldon. After all, it takes more than one element to make a Big Bang.


Conflict arises when Leonard's newly divorced parents and Sheldon's devoutly religious mother are all in town at the same time. And when Howard and Raj are contacted about the guidance system they've developed, they assume that the government is out to get them. Laurie Metcalf, Christine Baranski and Judd Hirsch guest star.
