1) mal said on many occasions that she was going to have a baby, not a dragon
I think any mother, when describing her offspring, wouldn’t note its species. She’d just call it her baby.
2) eight of their friends/ confidants were hatched from eggs (rip stealthy)
Do Snow and Charming know this?
3) mal has the ability to be human or dragon. And she stays human a good majority of the time. So 50/50 chance it’d be a baby on that point alone.
Nah, all we (and they) can say is “We don’t know how it works”. Though I think that’s enough reason for Snow and Charming to say “This is a bad plan; let’s leave”.
I would have an easier time with this week’s episode if Charming went into a berserker rage at every mention of a dragon, given his introduction to the world beyond the farm.
