Deaths, revelations, mysteries and questions abounded as TV characters and fans were left hanging for months at a time. Here are some of our favorites.
OUTLANDER In the Season 2 finale, after a season of being separated by time, Claire discovered that Jamie survived the Battle of Colluden, meaning she could travel through the stones to be with him again.
THE WALKING DEAD Fans of cable's most popular show were kept guessing (sometimes angrily and resentfully) for months on this one question: "Who did Negan kill?"
JANE THE VIRGIN It was the moment that kept the show's title true through an excruciating summer hiatus: Did Michael live or die after being shot on his and Jane's wedding night?
THE FLASH When Barry decided to go back in time and save his mother from the Reverse-Flash, he created an alternate timeline called Flashpoint, and he's still trying to repair all the damage he did.
YOU'RE THE WORST The epic love story between Jimmy and Gretchen took yet another dramatic but oh-so-in-character turn when he proposed to her, then promptly got scared and left her stranded in the middle of the night on a mountaintop.
ORANGE IS THE NEW BLACK A prison-wide riot left at least one life in jeopardy and the potential for danger high: Will Daya shoot the gun at abusive prison guard Humphrey?
THE BLACKLIST NBC's CIA spy thriller did the unthinkable in the middle of its third season: It killed off its leading lady, Elizabeth Keen (played by Megan Boone) right before a long hiatus. It was several weeks before the show revealed she had just faked her own death.
ARROW Rather than putting it in a season finale or right before a long hiatus, "Arrow" presented its big cliffhanger -- who's in the grave? -- in its Season 5 premiere, and then played the mystery out via flashbacks throughout the season.
HOW TO GET AWAY WITH MURDER The twisty-turny Shondaland drama took it to the next level with #UndertheSheet, a season-long mystery that kept hidden the identity of a series regular who had been killed off.
STRANGER THINGS After a season-long search, the "Stranger Things" kids managed to find their missing friend Will and rescue him from the Upside Down, but in the final moments of the finale, a quick burst of a vision suggests the mystery is far from over.
