After the battle with Shadow knuckles, tails, sonic, and you had convinced him to stop his destruction and turn good or at least give it a chance and if he disliked it he could go back to his other way, then eventually managed to get him to join y'alls so called "Family" which he was reluctant too accept or agree to but eventually you had convinced him too try it, when he finally agreed the five of you Sonic, knuckles, tails, Shadow, and you all went up to the house Maddie and Tom staying behind in the Truck as they were going back out.

opening the door the other three immediately entered going off too doing their own thing

Knuckles:just goes to his 'Training room'

Tails:quickly went up too y'alls room aka the large attic, you all shared

Sonic:made his way to the kitchen for some food of course,

While Shadow and you stayed behind Shadow didn't mind you all that much you were at least more bearable than the rest he thought though despite this and his usual serious cold expression it was clear he was a tad nervous about this but entered in after you anyway as you started showing him around the house before stopping at the last room you were going to show him
