Well she is in for a surpise

You know that Cerberus was forbideen t leave the underworld he litterly can't or he would burn and just be teleported back into the underworld . He is chained to the gates of Hades.

Poor Hades and persephone are going to have a lot on their hands get to see how busy Thanatos is XD

Also the hounds that belong to thanatos go intoa  deep slumber and do not awaken till thanatos come back even if Hades ordered them they do not move or do anything.

Nothing is really keeping balance as Thanatos did that job and Hades and Persephone are....not the best for that job.

CHAOS!!!!!!!!!
