Widuna secretly eavesdropped on the commotion in the cave. She disguised herself as a snake hiding behind a rock after previously following Nathan.
She had found Nathan and Airin but Widuna deliberately did not approach them. She was happy to see Airin hit and suffering. Widuna was happy to see Airin being helpless.
After confirming that only Nathan who was stupid enough still wanted to side with Airin, Widuna then immediately left, plunged his body into the water, and followed the current until she finally arrived at downstream of the river that flows between the entrances of the Etona royal palace.
Widuna immediately changed her form, she entered easily, of course, thanks to her magic which made all the gatekeepers sleep then walked calmly and gracefully following the wide and quiet palace hall.
