When they arrive,however,it actually is Soren,now working for the Ultimate Destroyer,to avenge the loss of his fame.While Jesse tries to explain him that it's the wrong choice and the Destroyer just tricks him,Soren reveals that he has Wither ingredients with him,builds the Wither and jumps intp the portal before it's summoned.The Wither explodes and destroys the portal,leaving Jesse and Axel no choice but to fight him.After the fight,the Wither falls into the lake of lava with the explosion sound tellling that he is dead.The two reactivate the portal and go home.
They arrive back to the Overworld with Petra and Olivia arriving from the End and telling that they also met Soren who revived the Ender Dragon.While Petra and Axel are angry with Soren,Jesse can say that he's either mad,or evil or tricked or whatever.When Petra's like "for the last time,we can't beat the Destroyer by speaking if he comes to our world,we need something useful",Jack suddenly appears and says: "We need to go deeper." and the episode ends.
Plot B:
Pretty much the same,but Olivia instead of Axel,End instead of Nether,colonists look different,Endermen instead of Pigmen and Ender Dragon instead of Wither.
