James
Lily is your biological mother. Her style of parenting was to teach kindness and compassion for everyone. But she also taught you not to take shit from anyone. Lily encouraged self-love and self-confidence. She would always encourage you and always want you to succeed.

She and Remus teamed up to encourage your corruption.

Or at least that's how James would word it.

"How could you, Lily!? James cried. "I never thought you and Remus would ever betray me like this!"

Sirius
Your biological mother is Jem White. She, however, had passed away shortly after your birth, so you relied on your grandparents (her parents, who you only visited once in a while) if you wanted to learn anything about her. Sirius's and Jem's relationship started as a one night stand. They decided to try dating for the sake of their child and was successful in doing so. They were together for 7 months until tragedy struck. Since then, Remus has taken the role of being your stepfather. You love him as your own dad, and he made sure you never felt unloved.

Remus
Remus is your main parent, but Sirius is also your biological father. When the whole fiasco with the potion went down, Sirius's DNA was used. Why? Even Sirius and James themselves didn't know. Sirius assumed his responsibilities as your other father. Remus is generally a straight-laced parent, and Sirius balanced that out with his wild personality. He definitely would buy a matching leather jacket for you and exclaim you were his kid with pride. Like he would literally re-enact that scene from the Lion King when Rafiki lifted Simba into the air.

"IIIIIIIII DON'T KNOW WHAT THE FUCKING WORDS AARRRRRREEEEEE!!!! BUT I LOVE MY DAMN KID!"
