Young Sheldon Gave Mary A Connection To The Big Bang Theory’s Penny (But You Missed It)

Young Sheldon season 6 stealthily included an Easter egg that tied Mary’s secret boyfriend to Penny. CBS made a tremendous effort to tie the prequel to its flagship series during its early years, especially as The Big Bang Theory neared its end. As years went on, however, Young Sheldon started to establish its own identity by tackling stories that have no bearing on what happened in The Big Bang Theory. This doesn’t mean, however, that CBS stopped incorporating details in Sheldon’s origins show that are secretly in reference to its parent sitcom.
