10 Best TV Show Twists You Never Saw Coming
7. Walt Poisoned Brock - Breaking Bad
Breaking Bad never got one over on fans better than at the very end of its fourth season, when Brock (Ian Posada), the son of Jesse's (Aaron Paul) girlfriend Andrea (Emily Rios), gets poisoned.
Initially Jesse believes that Walt (Brian Cranston) poisoned Brock, but Walt manages to convince him that meth kingpin Gus Fring (Giancarlo Esposito) was actually the one responsible.
In the season finale, Jesse learns that Brock actually fell ill due to eating toxic berries from a plant called lily of the valley, seemingly getting Walt entirely off the hook.
However, the season's last scene shows the lily of the valley plant in Walt's backyard, revealing that he did indeed poison Brock and had concocted this entire scheme to manipulate Jesse into helping him kill Gus.
Walt may have been lost in the moral wilderness long before this act, but poisoning a child in order to "win" was pretty much the last straw for many fans - the turning point at which Walt was truly, unequivocally beyond redemption.
Leaving fans to meditate on this revelation for the better part of a year was as ingenious as it was cruel.
