Will the hint of the kid be shown in the next episode?
If it’s ONCE then I don’t think so. According the inshow timeline Robin and Regina had sex like…what 3 or 4 days ago? No one shows that early on. So unless they are doing a time warp, then the person who is preggers–if it is ONCE–won’t be visible until 4B However, this is something to keep in mind as spoiler photos get posted over break. Pay attention to what Lana is wearing.
I honestly don’t think that spoiler is about Once, since babies have been born, but have not changed the dynamic of this show. The only for any change like to occur is if Emma was pregnant.
