Then, Emily heard a sound coming from Kol, and in his sleep, Kol had begun to whimper. A man who was not willing to show any weakness, not even in his sleep, was acting in a way that was not like him. Kol was acting weak, and he was most certainly not that. 

With that, Emily had gotten up and left. It's not as though she wanted to leave, she did before, but once Kol had begun to whimper, from the loss of her touch, she was a goner. 

She wanted to stay with him, she wanted to take care of him personally and try to fix whatever was going on with him, but she had to go home.

At the Mikaelson compound, the family was shocked by the way that Kol had acted. They were all speechless.

 Then, as they were getting over their initial shock, Kol had then begun to move around as though he was restless again. Emily coming was helpful, but Emily leaving was not helpful. The Mikaesons realized this too late, and then Rebekah had rushed outside to catch up with Emily.

The said girl was standing outside the compound, waiting to see if she could get a cab.

"Emily, you need to come back to the Mikaelson compound. It's Kol," Rebekah had said breathlessly. 

Even though she was a vampire, what made her out of breath was her worry for her brother, not the short distance that it took to get to Emily. 

Emily's eyes had widened in shock. She did not know the full extent of this spell, and it seems as though it was only getting worse.

 Then, in a short time, Emily rushed back inside. She ran up the stairs, where Kol was, and she had eventually reached him.

He was still breathing heavily, almost as though his condition had not changed at all, which was not the case when Emily had left. Kol had seemed to be in perfect condition, not perfect because the spell was not broken yet, but he was better. 

Now it seems as though he's almost back to the way he was. That was the case that was present on the basis of his actions.

Elijah, Freya, Rebekah, and Marcel were all standing around Kol. Elijah and Freya were trying to keep Kol down, while Marcel was trying to help to the best extent that he could. There was not a lot that could be done, and Rebekah was standing right next to Emily.
