The way Eris departed from Rudeus was amazing

It is like a hole in the heart when someone important to you goes away from you but it's for a good reason. Eris and Rudeus traveled a lot so throughout those 3 years and no she is leaving.

and no to mention when Rudeus passed by Roxy at that moment that scene was perfect
