Hummm... Very interesting Feign. So that leaves just Suri and Arkain. Those two could become close while having fun during the outing trip say when they slip and scare something in the pond that causes the two to get tangled in a  n accidental seductive embrace. That could lead to maybe Suri possibly unbirthing Arkain by accident especailly if Suri is older has grown and matured quickly but still sexually learning about herself and Arkain being very very curious. Things can quickly get carried away and Arkain can be drawn inside. Arkain can not be changed into a naga but I thought it might be a fun trip inside. Just a thought .
