"Extant" appears to be getting darker and a lot more adult--I think they might have to change the rating to NC-17.

Last Wednesday's episode "Shelter" saw the show moved to its new time slot at 10 p.m. This is definitely an indication that the show is heading down some dark corners, and the cast appears to be taking more risks. "Shelter" was definitely a risky episode.

Halle Berry's Molly Woods, Goran Visnjic's John and Pierce Gagnon's Ethan drive to Molly's father's place to hide out. Louis Gossett Jr.'s Quinn, Molly's father, is a recovering alcoholic, though he does not want to go Alcoholics Anonymous meetings. This places a strain on the fragile father-daughter relationship.

Molly does not call or visit her father often, so she and her family showing up out of the blue makes everything worse, not better. The cause and effect of this situation leads Quinn to relapse and take a drink. Molly starts having visions of her ex-boyfriend. Ethan appears to be learning faster.

While the show has Molly at the center dealing with her pregnancy experimentation, or alien visitation that she had in space, Ethan brings the show back to Earth. The surrogate grand-father-and-grandson relationship is attempted but fails when Quinn tries to use Ethan. Ethan quickly realizes it. It is all too late, however. The Woods family no longer has shelter or protection from anyone or anything.

The Woods family is no longer safe from the International Space Exploration Agency (ISEA), not from Alan Sparks, and Dr. Barton can no longer protect them. Sparks has gotten more controlling, almost bullish. He is now using ISEA to manipulate Camryn Manheim's Barton to give them the location and information of the Woods family in exchange for seeing her brother who is in a mental institution. Barton buckles under the pressure and gives them what they want.

Meanwhile back on the island, Ethan gets kidnapped by the Black Ops of ISEA, and he is used to trap and stalk Molly in the woods. It works. And Hiroyuki Sanada's Yasumoto is gearing up for Molly's arrival.

As Molly is captured, John and Quinn try to get help from the local sheriff who only laughs at the fact that Ethan is a robot, and they believe that they should not be wasting their time looking for him. This does not go over well with John. He attacks the sheriff, and he and Quinn spend a night in jail.

When did the show go all X-Men? Molly is at the mercy of ISEA and Yasumoto. She lays in bed drugged out and awaits to have her baby dispatched from her by force. The unborn baby exhibits telekinetic abilities that allows Molly to subdue the guard and attempt to escape -- but to no avail.

ISEA, Sparks and Yasumoto have what they want: Molly's baby. Is it a medical miracle or an experiment gone wrong?

Speaking of experiments, Yasumoto is pushing ahead with his own experiments. In a lab at the ISEA, he recruits the help of two German scientists that are trying to replicate the healing properties of some creatures. Molly's pregnancy might be the key. Just like Molly, Yasumoto reaches a critical point in his testing that leads to failure -- one of the scientists dies during the test.

Is Molly's baby really the key to everyone's problems? Can it save Yasumoto from death? Can they all see their dead loved ones? Everyone is in danger, and no one is safe anymore.
