Nyx with her seer powers, unless Ryo pulls the same stunt Misaki did with the poison blade.

Nyx is too good in my opinion. Like she's way too OP. Only Ryo and Portia are even close to her skill and their still a long way off. They need to ramp up the other's skills so they can keep up with Nyx. 

Hold on, I haven's watched that episode. They killed Nyx? I mean, I saw Milo's death, and I was like okay, and I saw Devon's death and I was like 'never really liked him' but Nyx? They killed her? I actually feel the same way I felt when they killed One that's saying a lot cause I was really attached to one. 

NOOOOOOOOOOOOOOOOOO

Oh, I'm sorry I thought since the shows been out awhile, and with you hanging around the wiki you would have been caught up. :(

I'm Nigerian. We aren's particularly the most up to date. 

A moment of silence for Nyx on my end. :( 

Ah, I understand now.

silence

It isn't 100% certain that she is dead.

The episode ended with Nyx on the floor, poisoned, and Android trying to decide what to do.

She probably is dead, but maybe Android can do something, maybe.

On the other hand everybody else was left near death as well, or in danger of death as the station explodes, so maybe Nyx will survive and someone else dies.

In any case, I think it very likely that not everybody will survive to season 3.

I think it's likely that she's dead. While I'm not a hundred percent sure, there have been a couple sources that claim she's not returning. If this is to be believed is up for debate, however, her actress is now on a new show now called Gypsy.

Yes, Nyx unfortunately is dead. It was confirmed in S3 E1 being better is so much harder. The Android has communication with the Mauader and she apologizes for Nyx. Later in the episode, Two suffers from lack of oxygen and hallucinates Nyx, where they say goodbye
