Calm?

[Third Person POV], 

Ace didn't know what to do as he stared at the unconscious elf lying on the ground in front of him.

Since killing her was his objective prior to the tree branch giving way, he was still able to do it.

He had wanted to kill the elf because of all the hidden threats she posed to him, especially in light of the fact that she belonged to a different race that might be unfriendly to those who aren't of their kind and similar to their own.

Ace thought it would be troublesome and didn't want to worry about something he didn't want to worry about, so he decided the simple solution would be to avoid all of this.

Kill the elf. That was all he had to do, and after clearing up his traces and tracks, he knew that at least one potential reason why he may run into the elves again in the future had nothing to do with the one standing in front of him.

Ace had no issue deciding against killing the elf for this and other reasons.
