Of course the hunt for Luna couldn't be easy!

In this exclusive clip from this week's episode, the Rover gang—Clarke (Eliza Taylor), Jasper (Devon Bostick), Octavia (Marie Avgeropoulos) and Bellamy (Bob Morley)—encounter more than just crappy weather and road conditions. Turns out, that map in the late Lincoln's journal may have steered them in the wrong direction, as well.

Still, the dead end does have a silver lining: Another awesome, primal performance from Avgeropoulos, who has been killing it ever since they killed off Ricky Whittle's Lincoln.

Check it out.
