With “Lost” finally getting evicted from ABC’s programming island, where will TV’s sci-fi puzzle junkies go to get their fix? Here are some shows that just may produce the smoke monsters of tomorrow.

Caprica

Friday, SyFy

Those who enjoy Jacob vs. Smokey, Jack vs. Sawyer, or Locke vs. sanity should relish this tale of two rival families clashing over the development of the AI that leads to the Cylons, which was about as good an idea as the Oceanic 6 returning to the island.

Supernatural

Thursday, CW

Digging Jacob and Locke’s constant returns from the dead? Then dig “Supernatural”’s Winchester brothers, who revive and die with similar logic-defying frequency.

Fringe

Wednesday, Fox

Can’t get enough of this season’s parallel timeline? “Fringe”’s mysterious “The Pattern,” introduced with a seemingly supernatural plane crash, will keep your brain exploding for seasons to come.

Stargate Universe

Thursday, SyFy

The inhabitants of the ship “Destiny” are stuck in a distant corner of the galaxy, unable to return to Earth. If we even need to explain the parallels. . .

Doctor Who

April 17, BBC America

The British legend, the longest-running sci fi show in history, returns. Those who pine for Jeremy Davies’ Daniel Faraday will relish the intellectual geekery of the bow tie-wearing eleventh Doctor Who, Matt Smith.

Warehouse 13

July, SyFy

Miss the “push the button” days of the Swan? “Warehouse 13” sends two secret service agents into a top secret facility to care for every bizarre, UFOish artifact the government ever unearthed.
