Dr. Kabir gets interrupted by Lt. Lane, with him trying to figure out how she found the cure.

He convinces her to get some sleep while he watches the empty medbay.

He finds the information and immediately confronts Garnet about her being a clone.

He wants her to relinquish command and threatens to call a vote to make her do it.

They gather the committee and vote, all voting in favor of Garnet.

She confronts Lane VERY professionally.

Eva wants to get the engines up and running.

Dr. Brandice finally tells Dr. Brandice about Eva's motive.

Felix approaches Eva, and Eva locks him in the room he's in and sucks the air out of it.

She argues that she's smarter than whoever did it.

One of the engineers has some sort of chemical explosion in his pretty face, and he tries to emergency stop everything but can't.

The bridge notices the issue and cannot contact the engineer.

Alicia talks a bit with Baylor about their date and needs a do-over.

She talks about her mom, and he tells her who he saw, and we get a flashback to their romance.

Alicia gives him a quick kiss, then he kisses her deeper.

Eva arrives at engineering and sees the radiation leak and the dead engineer.

She reports everything to the bridge.

Angus questions the mission, and Alicia's mind is elsewhere.

Felix talks with his assistant about trying to figure out who sent Lane that cryptic message and they know who did.

Lane sees Brandice.

Angus starts running out of hope.

Alicia?!?! Gets arrested for the murder.

Felix reveals that he knows she didn't do it, and she thinks she knows who may have access to her passwords!

It's Baylor Trent. Her love interest.

He runs before Felix can catch him but doesn't get away for long. Felix arrests him.

They start interrogating him, but he's confusing everyone, and he admits to killing the imposter!

The ship goes into a lockdown, and Eva announces that the only way to do it would be a suicide mission.

Brice wants to do the suicide mission, but everyone disagrees.

Garnet wants to do it, and everyone is on board EXCEPT Lane.

Baylor Trent wants to do it, and he tells Lane something.

Lane vouches for him, and they plead the case to the committee.

Trent suits up and heads out the lock to the radiation leak.

Eva opens the first bulkhead, and Trent takes off running.

Eva continues to open the bulkheads as he makes around each bend.

The feed starts cutting as he gets to higher radiation.

Trent gets to all the people that died, and the feed cuts out.

The radiation starts to hurt him, and he can't get through the last door.

He removes his helmet, smashes the lock, and tries to hotwire his way through the door like he did in the past.

He gets the door open and stumbles but manages to shut the engines off before he dies.

The alert stops, and the radiation emergency has been lifted.

Felix goes to Kabir to help her now that the murder is solved.

Lt. Brice approaches Dr. Kabir about the medical records.

Angus and Alicia managed to find a way to create a warning system if anything was coming towards them with that element.

Lt. Garnet goes to Dr. Brandice for help.

Lane finds a secret door thanks for Baylor Trent's confession to him.

The door leads to two cryo pods containing William Trust, the creator of the Ark Program, and his wife.
