2x13 - Yu Yu Hakusho

Okay, brief recap to what happened last episode: Kurama has just had his arms and legs frozen, but used his spirit energy through his hair when he used the rose whip to slice Gama apart. And like in the last episode, Gama tries to hit Kurama through his wounds, splattering his blood all over him. Right before he dies, Gama tells Kurama that his blood has sealed his spirit energy. Uh-oh. To make matters worse, the next member, Touya is ready to fight and avenge his dead teammate. Touya attacks just as Gama's first spell wears off, allowing him to move, but with his energy still sealed, he's still in a bad situation. Kurama spends all of the time trying to keep himself from getting killed by Touya's attacks. Eventually, he forms a plan to defeat Touya, and gets himself cut on purpose to plant one of his death plant seeds inside his own body right so it can manifest as a weapon.
