Okay I reread the story and I just thought of a better plot line for this story. I'm think a bit to see if I can squeeze it in and if not I'll rewrite the story.
As I thought it'd be more interesting if Tommy was the sole care taker to baby Dream. No one is able to tell the teen that it's his enemy.
So they get to watch Tommy take care of baby Dream who have all his memories but isn't able to hurt Tommy anymore.
Everyone in the smp have to watch Dream grow up with a protective Tommy, who almost broke off his friendship with Tubbo when he heard him threatening Dream.
