On that other note about Sam. There must be some trauma with either other creeper hybrids like him becoming feral and unstable or when they explode and left nothing but a crater behind. Which also made him become self-controlling about his emotions and keep calm.
He probably even forgot about one traumatic event that happened before he joined the server and was brought back when he was trapped in the egg.
gosh, I LOVE the idea that there are other creeper hybrids. and the idea of Sam not being the only one out there and perhaps having seen a fellow hybrid go feral/explode and seen the damage/repercussions of it himself? like!! yessss!! give me ALLL the angsttt!! Feralness!! Explosions!! Trauma!! WHOOP!
Could totally be possible! Sam with a sad/dark past is cool and epic. and the Egg reminding him of it??? ohhhh man, i would read 1000 fanfics about that
