Doctor Who: can The Doctor die?
Being a Time Lord gives him the handy ability to regenerate if his body is mortally wounded (or the actor playing him fancies a change). We know the Doctor can only regenerate 12 times in total, but does that mean he can't die until then? Mystery, consider yourself solved…
The Doctor can die if he doesn’t have time to regenerate. He’s been in this pickle a number of times, but has always gotten away with his life – so far…
Lost: what is the smoke monster?
Like a swarm of angry wasps, but made of spooky voices and bad memories, the black smoke has been scaring the Lost characters since season one. It killed Mr Eko and severed Rousseau's friend Montand's arm (those are some mean wasps). But what the devil is it?
The smoke monster is none other than Jacob’s nemesis, The Man in Black. He’s been on the island for centuries, and an encounter in the heart of the island turned him into the smoky cloud monster.
Twin Peaks: who killed Laura Palmer?
As Dale Cooper investigates the death of homecoming queen Laura Palmer, a closet full of skeletons tumbles out – not to mention the odd dwarf and haunted lodge. Her life wasn't so perfect after all, but who ended it?
The killer is Bob, the mysterious immortal entity from the Black Lodge. He possesses Laura’s father and causes him to do all sorts of nasty things. Spooky…
Angel: did Angel beat the demons?
"Let's go to work," says Angel at the end of season five. Did he, though? The show was cancelled, but the story continued in comic book Angel: After the Fall. What happened next? Did Team Angel beat the Senior Partners?
It all becomes a lot more series in the penultimate episode of the comic book series. Luckily, Angel manages to kick the demons out of L.A, so there’s a happy ending after all!
Nip/Tuck: who is The Carver?
"Beauty is a curse on the world," says The Carver, a madman who thinks physical beauty is evil and makes his mark by disfiguring his victims. Quentin Costa was a suspect until he revealed he was born without much of anything in the downstairs department. So whodunit?
Turns out it was Quentin Costa after all! The devil.
Torchwood: is Jack the Face of Boe?
Rose Tyler made him immortal, but it's been hinted that Torchwood leader Captain Jack Harkness won't keep his fresh-faced looks forever. It seems he may eventually become the Face of Boe. Is that true, or just a red herring?
Unluckily for Jack (or luckily? we’re not sure), it turns out that he will become the Face of Boe. We’re not entirely sure how you go from human to enormous face though… We should probably ask Darwin.
24: does Jack Bauer ever pee?
If 24 happens in real time, why don't we ever see Jack Bauer going to the toilet? Does he have a hidden catheter? Is he a mutant whose superpower is not-peeing? Or are we simply not being shown everything he does?
Well it turns out that Jack was once filmed leaving a washroom, looking relieved, but the scene was cut. Guess you’ve just got to hold it in Jack!
Life on Mars: did Sam travel in time
Police officer Sam Tyler wakes up in 1973 after a car accident. But has he actually travelled back in time, or is this just an elaborate fantasy he's dreamed up while in a coma? Or did he in fact come from 1973 all along?
Poor ol’ Sam is in a coma. Even so, those are some pretty riveting coma-dreams Sam.
X-Files: what happened to Mulder’s sister?
When Special Agent Fox Mulder was 12, his eight-year-old sister Samantha disappeared. He became obsessed with trying to find her, but what really happened? Was she abducted by aliens, as Mulder believed, was she murdered, or was it something else altogether?
No prizes for guessing this one. It was aliens. Oh, and the government. We knew all along!
Quantum Leap: can Sam ever go home?
He's leaped into the lives of men, women and children. From police detectives to beauty pageant contestants, he's put right what once went wrong. Can he ever go back to living his own life, though?
Apparently he can. But being the good guy that he is, he never does – at least not in the TV series.
