Mini Theory #1:

Okay, hear me out...

What if Sparklez didn't die in S1 E6? I mean, Cassie didn't die in her sand trap, who's to say that Sparklez didn't die in his either? We never see his inventory, we never see him evaporate, we never even see where he actually goes. In fact, Sparklez' is the ONLY person who we never get to see their inventory at any point in the episode. Trust me I checked. Now, I know what you're thinking "But we saw Sparklez' chest!" Yeah, we did, but Cassie prepared everything ahead of time. More than likely, there was chest for everyone just like the paintings. I'm here to tell you that his chest was empty.

Now let's say he did survive, why didn't he come back to the others? (He wouldn't have been able to run away even if by some chance he did manage to escape the building because the zombies would've eaten him for a midnight snack.) Well I'd guess that he got lost in the dozens of tunnels trying to find his way back, or maybe just kinda camped out alone till morning out of fear. That's what I'd do 😐. Or- or maybe he did survive the sand trap but Cassie found him and killed him before Jesse and the gang could save him. If so...then I'm so sorry dude...Lukas said it best: "...That's a rough way to go."

Mini Theory #2:

Okay! Hear me out again!

What if The Old Builders were originally from the Underneath? What if that Hadrien, Mevia, Otto, and Harper, were able to nerd pile fast enough to escape Romeo's bedrock curtain? I mean, we've seen how fast the Old Builders are at building. What if Harper learned her highly advanced Redstone mechanics from living in the Oasis? Remember, The Oasis was a unbelievably highly advanced Redstone operated city. After they had escaped, they created the Games together as a new and excited way of living. But once Harper realized how power hungry Hadrien and Mevia were getting (just like Romeo) she opted to run away, offering Otto to come with her. But once he'd declined, she ran away by herself, eventually finding herself in Crown Masa. And we all know how that went down... :|

Anyway, I hope you liked these mini theories! Do you think that either of these are possible? Maybe you have more evidence to add? Tell me what you think in the comments!
