I read the novelization of Sonic movie 3 the other day, and while I was sad it didn't go all the way through the whole film, y'all I LOST MY MINDDDD
Here's some stuff it had:
Shadow feeling achy and sore after he was woken up and trying to understand why, wondering how long he was asleep
Maria being said to be "barely taller than Shadow"
Maria made drawings for Shadow and put them on the walls of the lab
A missing flashback scene where Shadow had a betrayal of trust moment from Walters BEFORE the incident, when he overheard a conversation between some adults at the lab. Initially they were complaining about Maria being there, saying her drawings were cluttering up the place and that she didn't belong because she was a child. Walters said that she kept Shadow entertained or neutralized or something, something that made Shadow sound like some kind of feral beast and completely undermined and disrespected their friendship. Then Walters noticed Shadow eavesdropping and tried to address him but Shadow ran off, hurt
Dozens of both narrative and dialogue moments of the Wachowskis referring to each other as "their kids," "parents," "brothers," etc., including a narrative moment of Knuckles thinking of the Wachowskis as "his family"
In a dialogue to Maddie, Tom outright referred to Sonic as "our adopted alien son"
Tails having anxiety about the chaos and mess he and the others tended to bring to the Wachowski home, his worrying that he would be too much, that it would make Tom and Maddie want them to leave
Maddie telling the boys that she and Tom loved them no matter what
Tom having a proud dad moment while listening to the boys resolve an argument on their own, thinking happily that they are becoming "kind brothers"
Sonic initially refusing to go with G.U.N. without Tom and Maddie, until the parents assure them that they trust him and the others to be safe
During the argument over the Master Emerald, Sonic was furious but also in actual tears
He was going after Shadow with the literal mindset of "avenging his father" (that's exactly what it says)
