Rätsel serves as the main villain of Season 3, though she's got history with Jin Makata that complicates things. As a Giver, she's ruthless in combat—her whole goal is to eliminate her opponents, driven by a deep hatred of puzzles themselves. She's determined to prove they're pointless, which fuels her antagonistic crusade.
What's interesting about her character is the stark contrast between her brutal public persona and who she becomes around Jin. With him, fans often note that she drops the hard exterior entirely, showing a softer, almost childlike side that makes her way more sympathetic.
Her name is German for "riddle," which obviously works on multiple levels given her role.
