Algumas pesquisas rápidas sugerem que o plano original era encerrar a série com o flashback óbvio :
“The last episode of the series will be [Arrow] seeing the [rescue] boat in the pilot,” said executive producer Andrew Kreisberg. “Every week is telling the origin story.”
Entrevistas mais recentes indicam que o plano é para 5 temporadas de flashbacks:
Arrow, as first imagined by Berlanti — the television writer/producer behind Everwood and Brothers & Sisters, among many others — when he got an overall deal with Warner Bros. three years ago and they asked him whether he was interested in developing any DC properties, is an origins story. The show is set to run for five seasons, each flashing back to a year of Oliver’s captivity. By the end of the show, Oliver will have evolved from the Hood to the Vigilante to the Arrow — to Green Arrow.
Eu não encontrei nada indicando um plano da 6ª temporada, mas isso é 2 temporadas fora. Geralmente mostra o plano 1 temporada no máximo.
