Midoriko watched as the space between Kagome's hands began to glow. Faint, but getting brighter by the moment, the outline of the infamous Jewel slowly came into view. Sweat began to bead on the young woman's forehead as if she were straining with all her might; Midoriko had no doubt that she was.
Kagome pulled as hard as she could but the Jewel was fighting, hard. When Midoriko said the Jewel might put up a fight, she thought she knew what to expect. Turns out, she had no idea- this was actually painful with how hard she had to strain to force the Jewel into this plane. The closest thing she could equate the feeling with was when Urasue tried to forcibly remove her soul. This time though, instead of the whole thing being ripped from her, it felt as if she and the Jewel were playing tug-of-war with it and it was being torn in two. At least with Urasue it had been rather quick.
On top of that lovely feeling, the Jewel was also playing mind games with her, trying to get her to falter, trying to distract her. It switched between horrid, grisly scenes of her friends dead, torn to shreds, and picture perfect, sappy, fairy tale endings. It was the worst case of good cop, bad cop she had ever heard of. The worst part was that it was working and the Jewel knew it. The thought that the Jewel might win was scary enough to her that it began that against her.
She was slipping and she knew it but she was already fighting as hard as she could. She didn't know how she could possibly put up more of a fight than she already was. That is, until the Jewel made the mistake of using the worst possibility yet: the Jewel controlling her and using her to kill all her friends. It then chose to pick out Shippo and show her worst nightmare to her.
The poor little kitsune cried out to her, pleading with her to stop, that he was scared and didn't understand what was happening or why she was doing this. The Jewel zoomed in really close to Shippo's face and the Jewel-controlled Kagome picked him up. He was shaking so hard that he had trouble speaking. Suddenly though, for just a split second, he stopped and was unnervingly still. Then he was screaming. It is said a picture is worth a thousand words and his tiny, childish face needed both 10,000 words and only one to describe. Agony. Mouth agape, eyes wide, pupils dilated so far that the iris was nearly nonexistent, he screamed like only one dying a horrific and tragically painful death can.
The picture in her minds eye panned out to show her what was happening. Ever so slowly, she could start to make out the rest of the picture: her hand on his back came into view. In a sickening semblance of comfort, she was rubbing his back but as she was doing this, her hand was glowing. She was purifying him. Not only that, but the Jewel-controlled Kagome was doing it excruciatingly slowly with only the intent to cause as much pain as possible before he finally died. By the time the entire image was in view, she could see herself smiling in a way that she had only ever seen Naraku smile and Shippo, poor little Shippo, was still screaming.
