We're still reeling after the bombshell that was dropped at the end of Castle Season 4, Episode 16, "Linchpin": Rick's dad might be involved with the CIA! It's safe to say that Sophia Turner has officially opened Pandora's Box.

We're not the only ones still baffled by the episode's epic ending. The folks over at TV Guide are equally intrigued, naming the twist one of the best so far this season, and we couldn't agree more!

Castle's in pretty good company. Quinn's car crash on Glee made the list, as well as Tyler Barrol turning up dead on the beach in Revenge. Check out the complete list here.

What do you think of TV Guide's choices? Does Sophia's claim that Rick's dad was in the CIA make your list of best TV twists so far? Tell us in the comments below!
