I'm sorry here's a theory

Rose rescued Lion and lion had this honor complex and swore to protect her instincitvely, then for some reason Rose hid Lion from the rest of the Gems. On a mission between Rose and Lion, Rose nearly sunk in a sand dune but Lion saved her then ended up sinking. Rose presumed he was dead after attempting to get him out of the sand, and returned to the temple, now not needing to keep her secret. Lion ended up surviving and sensed that Steven was the same gem as Rose Quartz, so he kept his promise when he met Steven, and continues to today.
