Cora watched the fight briefly before scouting around the edges of the ring. After a few moments of searching, she found the banker, though it wasn't hard to miss the flashy clothes and how he was taking cash from people who were betting. She studied them for a moment before striding up to the banker and smiling. "I got big money I wanna bet on the newcomer, the Alaskan guy. Thing is, the only way I can bet this much is not in front of beggars and slime." Cora flashed a smile and some bills that she had pickpocketed from people around the ring. She was glad drugs made people stupid.
The banker sized her up, "ain't you a little young to be flashing that much cash? Or is that your allowance for the week?" the banker started to laugh but Cora moved quickly to put a knife to his throat.
"Well, I guess that if you're going to be rude, I'll give you three options," Cora paused to thumb the bills in her hand, "thousand dollars for that bet to start the night and we transact everything in your office, I slit your throat and take your key to the office, or... I could leave and somehow the police will get an anonymous tip about this place. I hear buying off the police isn't cheap. Especially if you have to do it every week for a year. Your pick."
To his credit, he managed to remain somewhat calm, "... let's do business in my office."
Cora removed the knife from his neck. "Oh, good. I hate getting blood on my stuff. It's a bitch to clean off."
"Might want to lock the door behind you, or I fear things will go badly for you." Cora said, splaying herself out on the couch in front of the desk. Click. "Good, now, I'm afraid I was lying about that thousand dollars, good sir. I also fear you're gonna have to be beaten within an inch of your life. You know, gotta do this non-fatally and all that." Cora stood and teleported behind the banker, landing him in a chokehold to start, tightening her arm around his neck as he started to slip from consciousness. "I guess you'll have to make do with no air for a bit, but you'll wake up. Maybe in a hospital bed, but you'll wake up at least."
He scrabbled at her arm, and tried to claw her face, missing her face until he finally went down, his breathing slowed. Cora dropped him to the floor like a sack of flour that had bugs inside of it. When she took a look at him, she decided that he hadn't been beaten up enough yet. She started out by kicking his back, aiming for his kidneys first. She then moved around for his stomach, kicking for a few solid minutes before stopping and seeing if it was enough. She kicked him in the face for good measure. Any questions could be answered by saying he fought back, which was mostly true. He had tried to fight, but unfortunately he never managed to reach that gun in his waistband.
"Next up, anything that's not nailed down," Cora smiled to herself as she pulled a set of keys from the unconscious banker's pocket as well as liberating his gun for good measure. "Let's see what kind of dirty laundry I can air for you, sir."
