Callaghan moved to one of the corners she knew were the safest when it came to fight, and then she felt her palm pulsating with anticipation. Not that she had been a sociopath with a long history of violence, no. She just liked a good fight.
When she heard another step and managed to see the silhouette of the intruder, she jumped forward, reaching out her hands and pressing the baton to their throat. A loud hiss filled the air when the person attempted to catch a breath while Aria was trying to pretty much suffocate them.
"Ar..." she heard almost gurgling, and then she frowned, raised her eyebrow, eventually releasing the person a bit, but still not enough for them to be able to break free. "Aria, for... fuck's sake!" she heard rattling and she closed her eyes, inhaling and exhaling deeply.
She reached out her hand and switched the light on. A very bright fountain of yellow had illuminated the room, finally exposing the person Callaghan almost strangled to unconsciousness.
