Sadly, Lost will take next week off and not air a new episode until May 4. On Tuesday, fans will have to settle for a rerun of "Ab Aeterno."

But we can at least offer viewers one spoiler regarding "The Candidate," based on the photos posted below: Jack survives (d'uh!) and is quickly reunited with Sawyer, Hurley and company.

Why is Fake Locke holding an explosive? And what's going on with the prison-like bars in these pictures? Theorize away, fans. ABC gives away nothing. Your guess as as good as ours...

Below, you can also check out the first, official promo for the May 23 series finale.
