OK, firs t in the book, it says, lets review it: they where in Bella's kitchen, he got close to her, she didn't now the h*** Edward problem yet, so she was falling a little bit in love with Jacob so she let him get close and we can prove that i mean look at that picture.
So, they were going to kiss, but then the phone rings and interrupts everything just like it happens in all the movies. That's when Edward calls to see if its true if Bella died, well any way, i cant tell you all the story that's why there is the book, k where was i, oh, then they separate and don't kiss. That's the probability that they DONT kiss.
The probability of them kissing is that the director can change things from the book, like Twilight, it didn't like the book. And ,common LOOK at that photo again. See how close does lips are, tit could be real.
Well, What to you think are they or there not going to kiss???
