THIS is the girl he decides to have a relationship with?
Out of the gate, let me say I have no problems with her red hair and freckles, as I'm a "soulless ginger" myself with freckles galore.
But after the little stunt with the ecstasy, really, Frank? This is the party girl you want to date, after 2 movies' worth of telling the audience you don't like complicated? I feel like Tarconi would be inwardly groaning when Frank tells him Valentina will be joining them for their afternoon of fishing.
Furthermore, I realize something had to happen to provide the impetus to get the two of them in the back seat, but I don't believe Frank would've played her little striptease game. I feel like he would've (rather easily) grabbed her, yanked the key from her hand and thrown her in the back seat.
But, whatever.
