Not only was it a good move to put them in the police car together to talk..... think about it. Now Misty knows Tommy was at PCSO and now Tommy knows Misty had been there two days and each are worrying what the other might have said. They are playing them all against one another in many ways. All 4 of them IMO.
Or we could just end up with the two of them sitting back there pondering what Granny Hollars is gonna rustle 'em up for that first big Sunday dinner after she bails them out with all that re-ward money, whilst they sit around giggling, watching Ol' Joe go down for it all.
They're clueless.
