"[Raven] wouldn't be alive if Finn hadn't risked his life to get her the Grounder medicine, and he was there for her during her surgery. He held her hand through it all, and that was all time he could have spent looking for Clarke," Morgan told TV Line. "He only left because she told him to leave, and she did that because she loves him. She knew, in his heart, he wanted to leave and look for Clarke. It's all pretty mature."
