In The Big Bang Theory Season 9 finale “The Convergence Convergence,” chaos ensues when Leonard’s (Johnny Galecki) recently divorced parents (guest stars Judd Hirsch and Christine Baranski) and Sheldon’s (Jim Parsons) devoutly religious mother Mary (guest star Laurie Metcalf) come to town for a belated celebration of Leonard and Penny’s (Kaley Cuoco) marriage. While Alfred (Hirsch) and Beverly (Baranski) are at each other’s throats, there’s a little bit of attraction between Alfred and Mary. Also, Wolowitz (Simon Helberg) and Koothrappali (Kunal Nayyar) are paranoid that the government is watching them when they are contacted about their guidance system. “The Convergence Convergence” season finale premieres on CBS Thursday, May 12, at 8pm ET/PT.
