10 Buffy Moments That Hit You Hard

10. Cassie Can't Be Saved

In season seven's Help, Azura Skye (who has the best name this side of porn) appears as Cassie Newton, a student at Sunnydale High who has psychic powers and who is convinced she's going to die. Soon. She takes that belief to new Sunnydale High counselor Buffy on the Slayer's very first day at her new job, making what should be a transitional period much more frantic.

Buffy, of course, buckles down and sets out to save Cassie, as does the rest of the gang. Which is nothing less than you'd expect from the Scoobies by the final season of the show - but it's even more heartwarming because Cassie is a character you generally can't help but like. She's sweet if sad, and she seems like she would be a great addition to the group. You almost peg her as a future member of the gang.

So it's heart-wrenching when it turns out that Cassie can't be saved in the end. It's no mystical, magical calamity that claims her - but a congenital heart defect.
