If you’ve read Eclipse, then you know that Bella kisses Jacob just before the battle in Eclipse. It’s something that Jacob fans have always used in support of their argument and proven to be one of the biggest talking points of the series. Kristen Stewart talked to MTV about it as well.
“Bella gets to a point where the only way to save him is to kiss him, and what surprises her is she’s not only able to do it…”
She continued: “She can clearly see that he offers a really desirable path that [wasn't there] before, because she was so obsessed with Edward. She just had to like nothing else. She had no perspective, and so it’s a moment.”
