Continuity mistake: When Clarke gives Lexa Anya's braid, we see Lexa accepting it with her left hand and then holding it with both. The next time she's on screen, though, you can see her holding it in one hand, still withdrawing from Clarke. In the following shot, she has the braid in both hands once again. (00:29:10)
