What Happened to Scott and Steve?

Scott was killed by Ethan way way back in season one, when the survivors refused to return Claire to the others.
Steve however, was last seen at the end of season 4 getting onto the zodiac raft which was transporting people to the freighter. He was on the second batch which never quite made it to the freighter when the sky turned purple. So one can assume he arrived back with Faraday, though this was not seen...
