Poor Frank indeed. I think the only reason he became a suspect was because he came back after going MIA for awhile. I am surprised Ceaser was killed off too!
I never suspected Penny was an island baby I don't think. It makes sense that trips were being made off the island and Charles was conducting them. It makes you wonder how many of those who were banished really did off the island. If they were born on the island it's not like they had families or friends off..so they could've done the same thing. Who knows? It was great seeing the doomed Ethan too. Maybe Ben saved all the young children and babies when the purge occured?
