The 100 Season 7 is really leaning into its sci-fi elements in its final season, and honestly, we're here for it. The show's final season has a lot of questions to answer, not the least of which being what will befall Clarke and her friends as their stories come to an end?

Season 7 has divided all of our heroes, some by distance, some by time, and some by both! Meanwhile, a new threat looms on the horizon as a mysterious civilization with incredible technology at its fingertips has slowly begun to reveal itself.

Finally, Sheidheda is still running around, and he might be more of a threat than ever to Clarke (Eliza Taylor), Madi (Lola Flanery), and the people of Sanctum.
