As much as I like all the shabortion fics and Shane having body horror attacks and all
Shane gets pregnant early in the situationship era and goes through different reasoning:
He's young and energetic still, it would be easier to have a kid now, not later
He is not yet at the top of his carreer
Hockey players around him have families pretty early and he would like to fit in, as it is difficult for him to as is
He likes babies (toddlers not so much but it's a problem for future Shane)
Shane: I'm taking a paternity leave till September, my girlfriend has a difficult pregnancy
GM: Not the best time, boy, but fine.
Voyageurs: Why are you always with the kid, where is your Lily?
Shane: She's a deadbeat mom
Voyageurs: Ohhhh that's rough buddy
Ilya: CAN YOU PLEASE STOP CALLING ME A DEADBEAT MOM
I am writing it it's not a drill
Shane is living in Modern Family while Ilya is living in Muneca Brava
Shane: Why are you panicking the kid won't be yours on paper.
Ilya: WHAT DO YOU MEAN WHY (hyperventilating)
