10 Disturbing TV Show Storylines That Surprised Everyone

10. Walt Poisons Brock - Breaking Bad

Landing on precisely what beat acted as the definite moment Breaking Bad's Walter White truly embraced his new life as Heisenberg isn't exactly a simple act; what with this being a guy who was seen letting someone choke on their vomit in their sleep and blackmailing Jesse into helping him get into the meth business in the first place.

However, even with those and many other acts being undoubtedly questionable and often cruel, they all pale in comparison to the chilling storyline that involved Walt attempting to poison an innocent child in a bid to get Jesse to believe Gustavo Fring was the one responsible for Brock's dance with death and win back his loyalty in the process.

By somehow sneaking the Lily of the Valley plant into the vicinity of the youngster, a poisonous plant that has similar symptoms to that of ricin, Walt was able to pull off one of the most diabolical feats of manipulation we'd seen on the show to date, catching just about everyone off-guard with the frankly sinister lengths he'd go to in order to keep his goal of defeating Gus alive.
