TV’s Most Shocking Deaths: From [Spoiler] on ‘Game of Thrones’ to [Redacted] on ‘You’

Whether it's drama, comedy or something in between, TV show writers have never been afraid to surprise audiences with a memorable character death .

Back in March 1975, M*A*S*H became a TV death pioneer when Lieutenant Colonel Henry Blake (McLean Stevenson) died in the season 3 finale. The character was headed home after being honorably discharged from the army, but before he could make it, he was killed by enemy fire.

Some 21st-century shows, however, make M*A*S*H 's surprise death look tame.

Lost , which ran from 2004 to 2010 , became known for its shocking twists before the first season was even finished. In the April 2005 episode "Do No Harm," viewers were devastated when Boone ( Ian Somerhalder ) died after a plane fell on him in the jungle, and his passing was just the beginning.

Manifest , You , Game of Thrones and more hit series have also thrown fans for a loop by killing off fan favorites.
