If there were a season 8, then...
- After season 7 ended and Screech was the only member never left Bayside, he was made a new principal.
- Secondly, all the students were new, but they were never added into the season 8 cast lineup, only the the new faculty did.
- Thirdly, Screech returned to normality and made new friends in the Bayside faculty level and beloved one beautiful young woman.
- Finally, at the end of season 8, Screech and that one beautiful young woman transferred to another same type of workplace from Bayside and they both got married.
This is where it should have end.
