No but the urge to spend spend spend could be and she could only afford it with fraud... her mental health was badly affected not so long ago so I am wondering if this is is still part of it?
I cannot believe that Bernice would have done this, terrible can't be bothered scriptwriting at best. Wherever she has gone, she would have bought the ticket on her credit card too. Not sure she has a good enough relationship with DeeDee and her dad to be welcomed in Australia.... I hope we find out eventually where she is.
She cannot have much space on her credit card, or she could have used it to pay off some of the loan. Hope she can afford a few nights in a B&B. Preferably one without gold plated nick nacks.
