Okay so in my universe of 'Were Meant To Be No Matter What They Say' And 'Love Will Pull Through, If We Just Believe' Cody gets pregnant.

No one explains how it just happens lmao

So here's the logical explanation.

There's a magic one and a science one so you guys can believe either one I'm not too sure which one I'll go with but yeah... XD

1: Family Genetics

So, In the story, family members from Cerebia's side of the family have the ability to reproduce Asexually and I I'm a sucker for Cody taking his moms genes so...

Also Joe got his dad's genes so no he can't reproduce it's only Cody.
He can poop eggs tho lol

2: The Nexus' Gift

This is a more magical one.

This one is where the Nexus gifted Cody and KrakenKid the twins, as they were both guys and needed a heir. She also ( its a girl now yes ) knew how Cody longed for a child of their own blood, because adoption isn't really their own blood tbh ( he never told Kraken winky face )

So yea believe whatever you want but one of these will be the real answer
