After the end of the first season, Clarke opens the drop ship, seeing Finn and Bellamy hiding away as she sees the bodies of the Grounders.
(No Mountain Men appear, and Annya switches sides to join the "Sky People". )
Bellamy and Clarke lead the survivors of the 100 to the Ark, where she meets her mother. They live in peace, with the occasional attack from the remainder of the Grounders, but always win.
Clarke grows bored of that life, wishing to go back to the Drop ship, and tells Bellamy her wishes.
Bellamy and Clarke are leading the 100. She was never kid napped by Mt. Weather and never use the bomb at the drop ship.
She was knocked out and brought back to a village. When Bellamy finds her in the woods, she is severely injured. Bellamy attempts to help in a procedure that Clarke leads him through.
