Question: why did jaime go back to cersei?
Answer: “[Jaime] knows that Cersei's provoked Daenerys so much, and she's underestimated her enemy — usually Cersei's the one people underestimate,” Coster-Waldau said. “His whole life has been about trying to protect Cersei, and trying to be close to her.” He loves her — it's unconditional love, it's so ingrained in him.
