Should I be scared?

Ok, so I'm applying for this permanent job at the credit union where I am working and they just told me that they are going to do a reference check with my last 2 bosses. Believe it or not, my old News Director in El Paso actually liked me, and offered to give me a reference, so I'm not worried about him. But Jim was my boss in Yuma, and since Jim is not there, I guess they will have to check with Luis. And we all know how much Luis loved me. After all, he gave me a cake and all that crap when I left. Yeah, right. So am I right to be afraid that Luis can still hold power over me after I've already left his evil clutches? Or maybe I should tell them to call Paul. He probably won't remember me, so it's worth a shot. Damn them!
