Watching these three episodes brought to mind this comic strip:
Remember it, as I'll be referring to it again later.
We start with the immediate aftermath of the blast: the injured, the dying, the dead, and Clarke trying to process it all. Perhaps unsurprisingly all of our main characters have emerged relatively unscathed, but the emotional fallout of Clarke's decision to keep quiet about the attack is explored across all three episodes.
We get four reactions to Clarke's decision: Abbie's horror, Octavia's anger, Kane's understanding, and Indra's grim acceptance. Between them, I think that the show ultimately condones Clarke's decision: that it was a tough one, but the right one in the context of the war they're fighting.
