Soon enough, Sapphire is standing in front of the tree which has her Kris embedded in it. With that same gentle grasp she used before she takes hold of the Kris and pulls on it a few times but it becomes clear the she won’t be able to remove with the amount of physical strength she possesses. 
She pauses for a moment then places her right hand next to the Kris, the inner palm pointing away from the tree slightly to her left. She then clunches her hand into a fist and a noticeable ‘woosh’ is heard as the Kris seems to dislodge a bit but still staying fixed and the tree. 

“Of course . . .”, she whispers to herself.

She prepares to do the same action again but she suddenly stops and drops her hand next to her. A few seconds pass as she stands there apparently doing nothing, keeping her eyes closed behind that hood. To the more trained eye it would become clear that she’s attuning her exceptional sense of hearing to her surroundings.
A few more moments pass when suddenly she turns her head to her right looking in the general direction of her uninvited guest who has now stopped moving and is observing from the shadows. It is unclear whether she’s just scanning the area or staring right at said guest. She stares some more for a few seconds still not discernible whether she’s just spooked or has in fact taken notice of him.

Apparently satisfied with her findings she takes the tree in front of her into view once more.

“I know you’re there . . . so you might as well come out.”, she says in a low yet commanding tone, her confidence seemingly returning to her voice as well due to her no longer being near the large group of people.
