Only that one word had come out of this one's mouth. She had a sentence or two in mind, but she was far from being able to express her thoughts at the speed she was currently thinking them. Ah, but it didn't really matter, soon Sukuna was bending down towards her, hand cupping his ear, gently teasing her lack of continuity with her speech. She had something for him, and she'd even opened her mouth to try and speak again, but Ishtar beat her to it.
One thing the other goddess could be known for, was her impeccably bad placed timing. She was interrupting what was probably about to be a rather heated conversation. No matter, she'd deal with that after. It seemed Sukuna didn't take well to be interrupted and corrected Ishtar about the state of her assumption. The thing happening between him and Ereshkigal hadn't been 'fun' it had been 'hello'. Ishtar managed to look confused. "Hello? All of this was just hello. That's unreasonable, you're not keeping her so why lead her to believe something like that?" Ah, yes, she was letting her mental misconceptions come out in a moment like this.
As for the glowing version of Ereshkigal, she was currently blinking and laughing. She was called stable, but she figured that was a reference only to her source, even she was fully aware that the laugh she'd just let out probably counted as something crazed. When asked a question about her mental status, versus the idea of dealing with Ishtar there was only one way this young woman could answer. Her brain was indeed still fried, but she kind of needed it to be to do the thing she wanted to do. And then they could kill Ishtar. "Yes!" she exclaimed with a giggly bit of childish innocence. In this moment she stood and began casually skipping towards Ishtar, and with each step she seemed to be echoing. Right until she'd stopped right before the green haired goddess and she was once again both versions of herself. "You've already figured it out right? I'll follow your lead here~" said the copy. "Yeah, of course... I'm just... still a bit, you know~" she mused While reaching towards the chest of Ishtar she stopped gently right before she would have touched her skin. And at her current state of enlightenment she began to glow. She harmonized with the death based energy at the source of Ishtar, and began unraveling her source by taking that out. The other version of her watched with glee as Ishtar screamed. That pulling apart of her barely active source was something more painful than anything she'd ever experienced. "Help! Help! AAAAAAAAAaah! She's hurting me! Make her stop!" she screamed in agony as she struggled but had neither the muscles nor magical access to do something about the shredding sensation at her core. Ereshkigal was being none too gentle about it, all the while carrying on a normal conversation with her other self. "Did you decide on your name yet?"
