Twilight In 2020 - Tumblr Posts

Ok so I researched the twilight movies and noticed something that got me messed up.

In one movie, Bella punched Paul in the face out of anger, not only did she make in impact because he moved like someone who got hit.

Then a movie later or something, Jacob kisses her without consent, and she punches him. But....

She breaks her fucking hand. I don't get t, because she didn't break her hand when she hit Paul, and Paul had phased already too. Is it because Jake's a descendant of an alpha or because he's a main character? Like how the heck.
