Robin 兜帽, 罩, 发动机罩 BBC - Season 4 //Heavy Spoilers to Season 3//

OceanCoast I think they announced awhile back that the show was not returning. Season 3 had the lowest ratings of the entire series, and with absence of most of the cast (even though Archer was set up as a replacement) the ratings would only get worse, so they decided not to renew.
