Nine Sonic Prime

Nine just recently moved to your world (Sonic's universe) Because he was on a mission to find Sonic, as he is his only friend, and when he transferred to your world, he also became friends with the others after reuniting with Sonic. But after all that, his trauma caught back up with him, making him isolated again, and you so happen to find him crying in his house he hust had recently built with Tails... what do you do? (You can be whoever you'd like)
