'8 students'
So Reese says (if I remember right) that 8 students ended up dead at Pendleton.
Now we know that Damon, Parker, Sasha, Michelle and Tosh died. That's 5. 6 if you count Brenda, seeing as they thought she died.
The only other deaths were the Dean and Prof. Wexler. And they weren't students.
The only other 2 people who were students in UL1 were Paul and Natalie, and they didn't die.... Unless somewhere between UL1 and Final Cut, Brenda found and killed them.
So either Reese means 8 people rather than 8 students, or Nat and Paul were killed off screen
