[ She did do it to kind of mock her, but... N-Not really! Deep down she admires her sister. They just have a very rocky relationship. Part of that is the inability to apologize to each other, so of course Ereshkigal looks very offended at the suggestion. ]

A-Apologize...? To her?

[ The fake immediately laughs and shakes her head. ]

See? She doesn't want to apologize!

[ What begins next is an exchange where the real and fake goddesses start arguing, as if they've forgotten Hiyori is around. ]

W-Why would I? You're a spoiled child with no sense of responsibility... You even tried to steal the only thing I had!

And you killed me with seven stabs of your spear!!

I was defending myself and my realm...! And then the other gods forced me to break the rules and let you go back to the world of the living!

Of course they did, the world can't go round without the goddess of love and fertility around.

S-See? Even as a fake you're annoying...! You keep breaking every rules and doing whatever you want with no care for the damage you cause around you!

[ ... ... ... ... ... ... ...

This may go on for a while. That fake got enough of the real Ishtar's energy to keep the dispute going for millennia. Hiyory probably reignited something of an old feud without even realizing it. ]
