I'm also a reptile person.
When I had a bearded dragon (RIP Irwin) Wobie had no issues with him. However, I had Irwin before I got Wobie. I added Charlotte (a boa constrictor) to our family about a year ago, that's when Wobie became a snake hater. I think Wobie gets jealous when I hold her, because I put him in a seperate room. I wouldn't worry too much about your situation, because she'll probably get used to your new little addition soon. Maybe just give her a little extra love and reassure her that the dragon isn't a threat.
