Yusuke and Hiei fight for a second time.
Hiei decides to help Yusuke and the others.
Gourmet's power is reveled.When he eats someone he will gain their power.In an earlier episode he ate Elder Toguro which is why he has his powers.
Yusuke uses the Shotgun again after a whole season not counting the time Genkai used it.
Fans debate on who is stronger Hiei or Yusuke.It is hard to tell since Yusuke was tired and Hiei was only fighting Yusuke so he wouldn't get angry and make stupid mistakes when confronting Sensui.It is most likely Yusuke and Hiei are even.
