Young Sheldon Season 7 Will Feature Key Character Return After 3-Season Absence (With Potential TBBT Connection) (https://screenrant.com/young-sheldon-season-7-tam-return-confirm/)

After a three-season absence, Young Sheldon season 7 will feature the return of a key character with a potential The Big Bang Theory connection.

Young Sheldon’s Big Bang Theory Returning Character Will Only Make Their Plot Hole Worse (https://screenrant.com/young-sheldon-tam-return-big-bang-theory-plot-hole-worse/)

Young Sheldon season 7 bringing back a long-forgotten character will only make their The Big Bang Theory's last-minute cameo more confusing.

So let me get this straight: you have friends when you're a kid and they HAVE TO FOLLOW YOU OFF TO COLLEGE AND BEYOND? Says who? Where's it written? Tam didn't need to be anywhere near Cal Tech. He was a damn high school chum, that's it. Again, the SELF ABSORBED TBBT FAN BASE STRIKES AGAIN where they can't get over their self importance. This is a non-story. No reason for Tam to pop up in Sheldon's California life at all.

Again, you all never had friends in grade school who you NEVER SAW AGAIN? Geez, you all are too much!
