1. Is Ben now officially bad? He’s always maintained that Widmore’s the big bad, but Ben’s actions this episode seem selfless and remorseless. Whereas Widmore seemed concerned for the island and its people, Ben’s only aim appears to be to get back and once more seize control for his own gain. Should we now be rooting for Widmore?

2. Is Locke now fully alive again? Christian Shepherd’s reincarnation only extends to lurking in the undergrowth and hiding out in a dank, old shed. Yet, Locke is walking around, talking to folk. Does he need to stay on the island to live now? Is he just a hallucination? Will he ever say no to someone who tells him that he’s special?!?

3. How long will it take for this new lot of plane crash survivors to die? Unless you’re part of the Jack and Kate crew, you won’t survive long on the island. We’re giving this new lot a couple of episodes before they’re burying each other alive after being bitten by a medusa spider.

4. Where has Frank sailed off to – and with whom? We’re told the pilot and a female passenger have taken off in one of the boats. Perhaps not all the Oceanic Six flashed off the plane. We haven’t seen Sun yet since the crash – Ben wasn’t happy to hear Jin was still alive, so could this affect Sun’s chances of meeting the other surivors?

5. Who is Walt’s counsellor? Because we could do with his number. Has there ever been a more well-adjusted teenager? His mum’s dead, his plane crashed, he was kidnapped by fake-beard-wearing baddies, he may have psychic powers (until the producers got bored of that), his dad ran off and left him again… And yet he didn’t even ask how Vincent is!
