Ginormous Bug

Hi, I started playing Minecraft a few years ago. During that time, Minecraft was around its 1.9 or 1.10 phase. This may be one of the latest close encounters. 

I was playing about 5 years ago on a Kindle, and I encountered this guy with completely white eyes and he looked a bit like Steve. I was only six, so I got scared and left the world, and I did some research to find out that he was Herobrine, a glitch that wanted to destroy my world. I didn't have multiplayer or Realms, so it was some sort of "non-existent player". While doing even more research, I found out more about his origin story in 1.8 and his children, Spidroth, Vioroth, Slmioth, Necroth, and Enderbrine. I wanted to see if the world was safe, and I came back into the world. I was high in the sky standing on nothing but a block of bedrock. I was pinned to the ground, Then Herobrine spawned in front of me. He started typing in the chat. This is what he typed: 

"hjalp" 

I went into Google Translate and found out that it meant "help" in Swedish. 

"Om du inte hjalper mig ar det HANS spel nu." 

This means "If you don't help me, then it's HIS game now." in Swedish. 

There was one question: who? 

I thought, maybe Null, Entity 303, Entity 404, or even Corrupted Steve? I wasn't sure, but I didn't care. I was chatting about the world with my friend while playing it when it said this: 

"Your 'Minecraft: Pocket Edition' was deleted for the following reason: Om du inte hjalper mig ar det HANS spel nu."

This question popped in my head when I started doing more research on Herobrine and Entity 303, and the question is: What is going on?
