@Stryzzar - Hawkman in Legends of Tomorrow was considered main cast and he died in like 2 episodes. In Supernatural Sam and Dean are in every episode yet Castiel doesn't appear as often but is still considered main cast. In Smallville season 10 Chloe vanished for most of the season and made only 5 appearances total yet was still considered main cast for that season. Again who says they're going to stay main cast? They could be credited as main cast to cover up their death. Walking Dead did the same to cover the identity of Negan's victim in 6x16/7x01 and that character was still considered main cast in their sole appearance in seaosn 7. Anything is possible and I think not losing at least one main cast member to Prometheus' endgame will be stupid.
