Will They Find Answers? - The 100 Season 4 Episode 4

Will Abby's group find the answers they're searching for? I'm assuming that her mission has something to do with tracking down more nightblood, to create a vaccine against radiation poisoning.

This is such an odd group of people, working together for the very first time. Interestingly, Clarke and Bellamy are nowhere to be seen in these photos of the group who goes on Abby's mission.

The details of this mission have yet to be revealed by any trailers for "A Lie Guarded." So far, we only know that Abby is commanding a quest to "find answers." What answers she's looking for – well, that we don't know just yet.

Nyko and Luna - The 100 Season 4 Episode 4

Are Nyko and Luna sticking around or leaving? Luna is the last of her people, the only one to survive her acute radiation sickness. The bag seems to indicate she's either leaving or setting out on the mission with Abby and the others.

I guess it's true that the end of the world makes for strange "bedfellows" – Murphy is the one who caused Raven's permanent physical disability, the root of so much of her pain. Yet, here they are, standing side by side.

Murphy's Game - The 100 Season 4 Episode 4

On "The Four Horsemen," Murphy made a point to help Abby out with attempting to save Adria, Luna's little girl. But his act of kindness wasn't purely out of the goodness of his heart. As he told Emori, they need to make sure they're on the inside of Alpha Station when the door closes -- he's trying to ensure their survival at any cost with his machinations.

Murphy and Emori ("Memori") are loners who have found one another. They're each always used to looking out for #1 (themselves), but how will that change now that the apocalypse is coming?

Now more than ever, Clarke is seeing things from the former Chancellor's perspective. While she just saw him as a ruthless and unfeeling dictator before, she now realizes that he made tough choices to ensure the survival of his people.

Can't these poor kids ever catch a break? Monty and Harper just solidified their relationship but have had no time to enjoy it. Hopefully, both of them manage to survive the oncoming acid rain and radiation fallout.
