The Movement rescue mission convoy creeps through the fog.

Luke is hearing voices again. 

Luke explains the alien shard to Ryder.

The voices warn Luke of an alien trap.

They lose a couple of trucks in the attack but seem to be escaping.

Then Clark comes upon an overturned truck blocking the road. In trying to avoid it, he rolls his vehicle.

Jamila and her party arrives in Paris as evacuation sirens sound.

They come upon a wall of photos of missing people.

Alfie convinces everyone to leave notes on the wall for any loved ones that might follow.

They decide to rest up at the home of Monty and Penny's parents.

Monty brings up the unpleasant possibility of Casper not even being at the hospital.

Recounting her time immersed inside the alien entity for Nikhil and Maya, Mitsuki recalls seeing a boy (Casper).

Mitsuki's hand is shaking but she wants to go back inside the entity.

Maya argues against the idea but Nikhil overrules her.

At the Movement crash site, Clark has a serious cut on his leg and Aneesha uses Luke's belt as a torniquet.

No one can understand the voices Luke is hearing.

Maya insists Mitsuki tell her all about her relationship with Hinata, which she feels the entity is using to control Mitsuki. But Mitsuki storms off.

The Movement survivors find Clark's party. They agree to hike out before dark

Jamila reaches out to Casper in her dreams but can't connect with him.

Monty has determined his father kept his mistress in Paris.

Still, he bucks up Jamila who is having doubts about their mission after her dream.

Mitsuki reenters the chamber with the alien.

The entity again adopts Hinata's voice. 

It encourages her to take off her helmet and she complies.

It invades her mind, taking her to a beach where Hinata played as a child. 

Tomas figures out Mitsuki's tremors are actually Morse code, spelling out "magnet."

Maya activates the electromagnet, which pains the entity and causes Mitsuki to pass out. 

Jamila and her party arrive at and search the trashed hospital for Casper.

Jamila finds Casper's abandoned headset and gives up hope.

She apologizes for dragging the others along on what she now sees as a fool's errand.

The voices warn Luke of looming danger.

They've come upon a group of hibernating aliens and have to run away but are getting picked off one by one.

They reach the Movement advanced contigent but Aneesha goes back in search of the missing Lucy.

An alien cuts off Aneesha and Lucy as they return but Luke somehow stops it with his mind.

Luke is in its head and he buys time for everyone to escape.

When Mitsuki awakens, Maya plays the new frequencies from the entity caused by the electromagnet.

Mitsuki realizes it's the aliens' language, which she can now study and learn.

As they're leaving the hospital, Penny hears a noise, which turns out to be Casper, who is drawing on a wall.

Casper, who everyone is hoping can help them defeat the aliens, can't remember what's happened to him recently.
