Why didn't they have more children?
They really should have had more kids, because Melody sucks. Really though, Ariel comes from a huge family, and she and Eric love each other madly and are presumably shagging constantly, so what gives? You only had one kid in the 13+ years you were married? And no male heir to the throne, since this is late 1800s Denmark presumably? For shame.
What about a cute little redheaded boy? What about a whole gaggle of little human-hybrid merbabies? What if they had cousins if Ariel's sisters got married and brought THEIR kids to come see Ariel's kids?
What if the plot had been more along the lines of a cross between The Incredibles and The Sound of Music, with each character having different personal stuff going on in a climate of change and upheaval? Such as Triton's death or something. Does the crown go straight to Attina, the oldest sister (based on the prequel), or does someone challenge her for it?
Your thoughts?
