What to Expect in 'XCV'

The synopsis gives away what episode 4 of this season will be all about. After falling off the tree following a deadly showdown with the Daughters of Aku, Jack will find himself inside the belly of a huge monster.

Escaping will be harder than he can ever imagine, because the monster's belly is filled with gastric juices that melt down anything. In the preview, Jack was seen testing the acid's corrosiveness by throwing a piece of metal arm band into the pool of death.

But not all hope is lost. Hovering over are jelly fish-liked creatures. Jack thinks if he can just hang into these things, he might find a way out of this mess.

Unfortunately, Jack has to deal with a former enemy. Ashi, the surviving member of the 7 daughters of Aku, is still seeking vengeance and at the same the fulfillment of her destiny as the conqueror of the Samurai.

Jack should find a way to tame Ashi's bloodlust, for it is the only way they will ever get out of the monster's belly.
