   Summary

   After realizing that Susan’s love only ever seemed to orbit one twin, Roderick quietly stepped in to raise the other.
   Now, between school, band practice, and nap times in the garage, he’s learning that being a brother sometimes means being everything at once - guardian, best friend, and home.
   A gentle AU exploring what happens when little Greg grows up loved, not forgotten.

   “He wasn’t supposed to raise a kid. But maybe he was always meant to be someone’s safe place.”
