Wait that tattoo looking thing on koichi looks like a womb. Is he pregnant now?

Dunno if he’s pregnant but I do know it’s his mark of being the Titans bride

Maybe the magic that bings caius and koichi together that caius mentioned if he came in koichi could make him pregnant? I mean it's possible? Like if that mark of being the titan's bride could be how koichi gives birth?
I'm just hoping cos I love gay parents.
