We can't blame the two that much, because while Reshtoka and Aurora did literally not communicate ONCE with Karina.. Karina also never, not once, told anyone how she felt. She just did as she was told, getting angrier and angrier, without actually speaking up to anyone.
Sure, it was hard for her to speak up for herself, but she could do it now. She could talk to Reshtoka. She could talk to literally the fucking trees, but she won't. Because while she in a way can't, she's also too prideful to say it outloud.
And in a way, thats why this story works. But also why it doesn't.
Because while the issues are human and touching, they're also INCREDIBLY FUCKING FRUSTRATING. Someone, anyone, please open your mouth! COMMUNICATE. AUGHHH.
