I have a theory!

The portal hallway is set up in a dimension, (it has to be) and wouldn't that mean that they could just mine their way out? Some of you might say, "Kenzie, those would take forever to mine through." But Harper did it no problem in episode 7. So maybe the Atlas is a tutorial on how to get out of the hallway, and they were in their world the WHOLE time. If so, soren may have used the command block to make a STRUCTURE BLOCK which is used to create the portal hallway.
The achievements for episode 8 sound like the hunger games, so maybe episode 8 will be like team Minecraft survival games? That's also similar to what it looks like in my dreams. When I'm asleep, I dream of Minecraft story mode 99% of the time, so sometimes I unintentionally predict the future of MCSM with dreams. Let me list a few:

1. I knew at one point, just making a decision, Could possibly kill you. (Dream that came true)

2. I knew that someone would come along, that everyone shipped ivor with. (Theory that came true)

3. I knew ivor would get a rose. (Weird talk with my friends)

So, it was a medium sized area, decorated with gold and iron blocks,
The entrance was made of gold, and there was small statues that were made of gold. Other stuff was made of iron blocks. There was a girl, she wore
A grey and dark gray shirt, she had blue pants, blue eyes and black hair.
Funny. I looked just like her. Twins. She even sounded like me, she said:
"Welcome to the team survival games!" And other stuff like that. It was probably nothing, but I couldn't help but think about how much she looked like me.

Toodles!
