Based on and around the fight Lexa has with Roan in season 3. After the fight Clarke goes to find Lexa and err, things happen. They talk, they bicker, Lexa is tense and Clarke is annoyed. So what else is new? Clarke helps patch Lexa up and there is some innocent touching that leads to some not so innocent touching. Some stuff with her tattoos and some stuff with her warpaint and oh, there's a LOT of sex. This is NSFW guys, you have been warned!
