Episode 3: Mysteries of the Dark Mountain. Officially introduces Entity_303 and entities. Important Events: The group of travelers finds Entity_303, and Pop and Nick learn about entities. Entity discovers something about Pop that not even she herself knew.
Our travelers have been journeying for several days to get to the Dark Mountain to get Entity_303, a six-hundred-year-old entity that can help them save the world. Rumor has it no one's seen his face since he had become evil long ago. (He's not, now.)
When they arrived, he actually turned out to be a pretty fun dude, despite his appearance!
After they told him about everything, he agreed to help them go to the Nether...
... knowing that only an entity could build and light a portal to any other dimension. Then he told them that he would make breakfast in the morning!
She thought he was nuts. He knew what this might've meant, but he wasn't sure.
Later, Pop was alone, but Entity came to check on her, seeing her,-literally- get struck by lightning; she hadn't noticed!
They decided to ask Herobrine about it... if they managed to track him down...
Then he remembered the virus that had possessed both himself and Herobrine. It was possible that it had returned.
