I definitely took out everything with his mom! Canonically his mom causes him to run away when he's 9 years old, so I gave him an AU where he's actually close to his mom and loves her dearly. I also gave him only the one sibling (Annabeth, in this case) instead of the multiple half-siblings he has thanks to being a Hermes kid. Item-wise I made him a fencer so it'll be interesting to see what he does whenever he regains Backbiter. AND OF COURSE I didn't give him any of his scars and since he has two very important ones (his facial scar and the scar under his arm from when he stabbed himself) those are definitely going to change a lot of how he responds to everything
