Roan gains the upper hand, but will he kill Luna — and with her, humanity's only hope?

Luna and Roan appear ready to fight — to the death, if necessary. What could have possibly happened to cause this turn? Has Luna decided she wants to go, leaving Roan to stop her?

Luna agreed to cooperate with Abby after Raven convinced her, but things might change now that harvesting her bone marrow is potentially the only hope of a saving grace for humanity.

Clarke has proven time and again that she's willing to do whatever it takes to save her people, and she showed little hesitation when it came to offering up the scavenging grounder for human experimentation — but who knows how she'll react when it's revealed that Emori framed him.

Clearly, everything is not going well with Abby's experimentation on the grounder who was caught scavenging and framed by Emori.

Has Raven's brain healed itself? Or is she still working herself, literally, to death?

Raven is awake from her coma. She's woken up just in time to witness something horrible go down, by the looks of everyone's faces.

Emori tricked everyone into using an innocent scavenger for their nightblood experiments on The 100 Season 4 Episode 7, confessing the truth to Murphy. Will their secret be uncovered?

Emori and Roan haven't had much interaction as of yet. What could they possibly be conferring about?

Based on the group's defensive stances, it seems that this meeting will take a turn for the worse sooner rather than later.
