Hide Away.

"I didn't see this coming," Ragnarok said ruefully. 

He is honestly afraid. His entire existence has been put on high alert ever since that attack. He knew instinctively that the danger wasn't over when he escaped. His intuition wouldn't let him relax after the skirmish with the ghoul. Now he knows just what kind of problem he has gotten himself to. He is in a situation where he knows that he is fighting for his life. The threat of the ghoul is that serious to him.

The ghoul has locked onto him and his coming straight for him. It is passing through every obstacle in the way as if they are not there. The ghoul can always find him no matter the distance and no matter which direction he runs in. It will just pivot toward his new direction and start moving closer to him.
