Maybe peter would be a child of Janus (from the other camp ofc.). Since he could have done the right thing and stayed with the marauders but decided to join voldey. It was a way more important decision for him tho since his dad is the god of decisions and doorways. Peter, like Janus, can never make up his mind and is very two faced. Opinions?
…that’s actually super clever. holy sHIT?? i don’t know how they’d all meet if only one of them is roman (sirius/james/remus just don’t strike me as roman tbh?) but, that’s a good idea.
i also like ananke / “The goddess of inevitability, compulsion, and necessity.” for peter :D
