Raven Reyes (Lindsay Morgan) might be one of the key persons who can help prevent the Earth's possible destruction when "The 100" returns for season 4.

During Dragon Con in early September, Morgan and the other cast members of the post-apocalyptic drama spoke as a panel to discuss what the fans should look forward to next season. One of the things that Morgan discussed was the changes that will happen to Raven after artificial intelligence A.L.I.E. (Erica Cerra) infiltrated her brain in season 3.

"It's like an upgrade. It's like when you get an upgrade on your phone and you like, 'S***! Everything works so much better now!' And you're down with it, right? But then, I think it's 'The 100' and everything isn't what it seems. So let's just leave it at that," Morgan said in front of the audience according to the video posted by Variety Radio Online on Youtube.

Raven has always been very instrumental in the survival of the 100 youths sent by The Ark back on Earth in season 1, using her expertise as a mechanic. Despite all the injuries that she received from the Grounders and the Mountain Men, she continued to become one of the assets of The Arkadia.

Since A.L.I.E. managed to alter her brain last season, there could be a chance that Raven will have all the answers to help Clarke (Eliza Taylor), Bellamy (Bob Morley), and the rest of the surviving Sky People and Grounders to save the Earth from a possible nuclear meltdown in season 4.

Meanwhile, speculations about the premiere date of "The 100" season 4 surfaced after the writers of the show uploaded a cryptic post on Instagram. The post showed a drawing of a perfume bottle with the words "Eau De Radiation." The perfume was mentioned to be available in 2017, but fans with keen attention to detail noticed that the volume of the perfume is 17.2 oz. This could mean that the upcoming season will premiere on Feb. 17.

The CW has yet to announce the official release date of "The 100" season 4.
