@Crombs for one, I am not furious at her since Legosi is not. Two, this is fictional. Fixed on outward appearance is indeed bad, but this is a different world and social structure than our ol earth with boring humans. As I understood it, mixed weren't that kindly looked upon in this society. I mean even Yafya think same species couple is better. Let's say that that means, to some extent, there is racism, but in form of species instead skin color/race. Gosha being a reptile is already being looked down on even to legosi's present day (remember the school guard?). So the why she did this is understandable. She's a coward, terrified of discrimination, after all her life using a mask, adopting that mask as what she define herself (being a wolf).
All in all, obviously, she is still one selfish bich. I won't be furious about that since Legosi and Gosha don't seem they mind, so why should I waste my time being furious on behalf of fictional characters? Legosi and Gosha seems to forgive her though so why must I had extra emotion for her?
I'd rather prefer to applaud Legosi and Gosha's action in this chapter. Big hearted boy and badass grandpa, that's the sht I'm here for.
