Tarentek was honestly quite a bit confused. He was not sure why Onyx would be angry at him for being afraid of heights, though it started to make sense once she brought up dropping him the last time she carried him. Evidently, she thought he just did not trust her ability to carry him. Admittedly, it was something that made him nervous, but he would feel the same way about anyone who wanted to take him in the air. It would be simple enough to tell her...he just needed to get up the staircase first. 

Fortunately Tarentek did not have much of an issue climbing the side of the mountain. He did not have to stop and rest, and was only slightly winded once he reached the top. As promised, Onyx was waiting for him just over the ridge, and before she could say anything, he spoke up. "You know, I'm pretty afraid of heights, kind of like what you are with water."
