Penny’s sister not having a physical presence on “The Big Bang Theory” may come across as strange, but there’s actually a bit about the character that remains shrouded in mystery. The biggest one is arguably how Penny’s last name is never mentioned on the show. However, her sister is mentioned periodically, and viewers do know that she’s married and has a child.
As much as fans wanted Wendi McLendon-Covey to appear in the role, it didn’t happen and may very well never come to fruition at this point. Then again, “Big Bang Theory” does seem to live on. The sitcom spawned the “Young Sheldon” spinoff, focusing on Sheldon Cooper (Jim Parsons) when he was a child. Now, “Young Sheldon” will spawn its very own spinoff that’s centered on Sheldon’s brother, Georgie (Montana Jordan), and his partner, Mandy (Emily Osment).
Similar to “Young Sheldon,” it doesn’t appear like there would be very much room to introduce Penny in the new Georgie spinoff. Of course, this could merely be the beginning, as it’s not entirely outside the realm of possibility for a genuine “Big Bang Theory” universe to materialize. Perhaps down the road, a spinoff centered on Penny’s family, including her sister, could come to light.
Above all else, Kaley Cuoco and Wendi McLendon-Covey are both fantastic comedic performers. There could definitely be a fun dynamic between them to the point where another spinoff practically writes itself.
