I never really understood Hiei's reasoning. I think he hated who he was/what he's done and wanted to keep Yukina out of his mess. Or something. I didn't care enough to think hard about it. Goshikuro knows Kurama's weakness is his friends/family but I think Goshikuro wouldn't provoke Yusuke or Hiei or Kuwabara since it's more of a personal matter than anything else. But to really stab the knife in, he will probably ensure Botan is kept away from the final fight. Hopefully he doesn't know about her budding powers (pun unintended).

You should sleep though, it'll probably be a few hours before this post is up. ^^;
