Once Kyle exited the cabin, he headed back to his sleeping cabin, feeling unhappy.
There were just too many loose ends to tie right now.
Cornelius had been taken care of, but it wasn't enough.
Just before he left, Kyle had altered Cornelius's memory of what happened in the room. To Cornelius, he had been successful in his r*pe, she had woken up in the midst of it and that he had scared her so much she ran out of the cabin.
However, Kyle wasn't confident of the success of the mind alteration as it was his first time doing it. Though he had done it with Samantha to make her believe they had sex, it was different because it was merely 'continuing the fantasy'. In this case, it never happened and there was a lot more work involved.
