Older paladins meeting younger paladins.
Lance LOVES Keith’s really long hair and is always messing with it. Braids, clips and simple things at first but as they get older and closer he ends up doing Keith’s hair almost every morning sometimes in pretty elaborate designs that he’s picked up from different planets.
Lance and Keith’s rings. Meteorite with special crystals found only on a single moon on a planet they visited. Also had they EXTREMELY private ceremony there. Bonding ceremony that binds their quintessence/ souls together. The rings act like receptors for each other’s thoughts. Telepathic rings All of this was Lance’s idea and literally had to kidnap Keith to get him away from their jobs as ambassadors. The minute Keith knew what he was doing he CRIED for hours.
