Lol, it's funny how she messed up her confession. But I don't think she's playing with Cabel's feelings, or at least not intentionally. I believe she genuinely likes Cabel too but she is just much more comfortable with Elvin. There were plenty of instances she got flustered and had her heart racing because of Cabel. She also always feels safe and secure because of Cabel. She said as long as she can see his back, she knows she'd be okay. It was also with Cabel where she had her power breakthrough.
I think she is just too intimated or still feels awkward around him. She might like Elvin too but I don't think she has realized how much she actually likes Cabel more.
