Battle of the Death inside the Water Prison!!

Summary
Since he is more agile once fused with Samehada while in water, Kisame creates a large water dome to fight Killer B within. Bee cannot survive under water for long and Samehada continues to absorb his chakra, so he tries to escape, but is followed and attacked by Kisame. Once Bee is exhausted Kisame separates from Samehada and tries to cut off Bee's legs to make him easier to carry. Samehada, having grown fond of Bee's chakra, stops him and protects Bee, even giving him back some of his chakra. Kisame kicks it away and tries once again to cut off Bee's legs.
