Yeah, like, MC and Rangi can just explain their side every since they met to the mob. The sister may try to use their words to spin a malicious tale, but I don't know, can't Rangi just ask her sister to put her name in the line if she was being truthful? Heck, MC got attacked by the bear clan for associating with Rangi. Also he got attacked by Pye then later by the snake woman, Pye is still alive so that means MC isn't bloodthirsty or crap like that. Rangi's sister may try to say he could have help and manipulated Pye but Rangi only has to say BS on that. The more they debate, the less the sister has defense because MC and Rangi's side is based on something that happened. Meanwhile the sister at best either has to lie, to misconstrue etc...
