MHOO but I feel like she would actually be the more suicidal of the two. She went into this fully knowing she would probably not make it out. I think it was her plan all along. She sucked her money dry like there was no tomorrow. IMHO it was all an elaborate suicide.
I thought his plan would be to suicide by cop so I'm surprised that it's him that's walking away (relatively) unscathed. I mean, back to prison, but.. alive.
