Only candidates can have babies on the island
For whatever reason, perhaps because the ‘ultimate’ candidate is a baby from two candidates, only candidates can have babies on the island.
Babies known born on island
Ethan, parents: Amy and Horace (Goodspeed has no number, but crossed off in cave)
Alex: Rousseau and Karl Martin (337)
Aaron: Claire (Littleton 313) don’t know if we ever got Thomas’ last name, which is weird ‘cuz his paintings show up on the show.
Baby Kwon was supposed to be born there (Kwon 42)
Maybe that’s why Ben (117) thought Juliet (Burke 58) was ‘his’ … with whom to have that ‘Next Jacob’.
And, the rule Widmore broke was to have a baby off the island. Penny. Perhaps making her a candidate, too – or excluding by non-island birth … or Desmond is bringing her to the island.
