The water suddenly started to bubble and Sacha quickly moved back in time for the boy to heave himself out of the pool closely followed by ???. He grabbed on to her arms and gently lifted the girl out as she panted for air, quickly taking out the list and showing it to her before stashing it back in his pocket. Before he could suggest that they retreat something whizzed past him, narrowly missing and instead embedded itself inside the stone cave wall. 

[i] "Ah, I'm sorry. Did I miss?"[/i]

He spun around quickly, stepping in front of their leader who was still gasping for breath to face the brown haired girl who had thrown the… meat cleaver? Why was this girl throwing around meat cleavers? She had another knife in her left hand as well. 

[i] "Next time, I'll take your head."[/i]

Of all the types of people this group of humans could have, they had a psychotic knife wielder murderer. Great. 

Discreetly he pressed the folded list into ???’s hands, not once taking his eyes off the girl. As he crouched slowly in anticipation for another attack. 

[i] "Give me the list and your head comes off."[/i]

Give her the list AND his head comes off? Well then.

Sure enough the girl dashed towards him, throwing the cleaver that curved towards him (great, it was a [i]magical[/i] cleaver. Just his luck.) preparing to slash at him from the right. With the pond behind he had no choice but to lunge at the girl, tackling her and throwing her back with enough force to throw her back a few meters. He felt slightly sorry for doing so as she was quite a bit smaller than him, but judging by the fact that she was actively trying to take his head off felt a lot less guilt than he usually would have. 
Sacha gestured at ??? who was still behind him to try to give the signal to leave now they had what they wanted. He didn’t want to spend any more time dealing with these people than he had to especially if there ended up being more than one person off their figurative rocker.
