I still don't get it. Between the novel and the film, I don't see how Carlo planned this. I mean, the fight Connie and Carlo had that day was completely spontaneous - Carlo's mistress called the house, Connie answered the phone, and she started in on him (starting with barging in on him while he's in the shower -*deleted scene).

So, for a whole year, based on Carlo's purchance to hitting his wife and having Santino find out about it, Barzini's people planted themselves at the Jones Beach Causeway? I mean, Santino left the mall many other times (to visit Lucy Mancini, for one), so Barzini's people could have ambushed him anytime he tried to leave Long Beach.

Just seems a terrible coincidence. Not even the novel goes "into it."
