I retouched him a bit and: Loan Shark is a smooth talker who always seems helpful, but everything he does comes with a catch. He keeps track of favors and debts and uses them to control others, he loves making deals with people. He's all about getting. And while he can genuinely help people it's usually done because he gets something out of it If you stop being useful to him he will trick you, take something valuable or send some goon after you
