When Hachikuji was first introduced in Bakemonogatari, there was this scene where Hanekawa punched Hachikuji. I feel that's pretty out of character especially after seeing more of her personality in the later part of the series. I took it as just a comic relief.
In Nisemonogatari, however, Hanekawa stopped Araragi from hitting Karen when Karen got reckless.
Are there other evidences showing that Hanekawa punching Hachikuji is not out of character?
