Bella is, first and foremost, a wolf. And she's about two years old. She has very little life experience, and much of that was out in the woods. Wolves are not renowned for their intellect, and though Bella's a Garou (and Garou are geniuses by wolf standards) this was what she was raised with. She prizes strength, smarts (though she has a hard time defining smarts), and glory. And she will bluster about her own meager glory as much as she can.

Secondly Bella's also quite young, so she's very impressionable and her Garou elders have left a strong impression on her. She sees the world in black and white and will zealously paint everything as such as she's been taught, though she's easily coaxed into contradicting herself if you present things to her the right way. She also has an excellent memory for rankings and needs solid leadership and hierarchy for her to function at her best.

She's naive and earnest and eager to please and has not seen a great deal of badness in her life, so she tends to be trusting of strangers if they pass the "do you look like a Wyrm creature?" test. Beyond that her tolerance for the bizarre is very high.
