Lost is returning to our screens this Sunday on Sky 1 with a special double episode to mark the start of the penultimate Lost series. Plenty of answers are expected, as are plenty of new questions as is the nature of the show. Who or what is Jacob? Who built the four-toed statue? Will Jack and Kate return to the island? How did the island disappear into thin air at the end of series 4? Where did the Lost island go? What’s happened to Locke, Sawyer, Claire and the rest of the gang? What is Charles Widmore’s real aim? Will Penny and Desmond live happily ever after? Why was Locke in the coffin in the flash forward? Is Ben good or evil? What is the Black Smoke?

So many questions to be answered in just 2 seasons! If you’re new to Lost or need a refresher on what’s happened over the last 4 series’, you can now buy the box sets of seasons 1-4 of Lost online.
