Same vibes here. The way they were holding Hama reeks very much of a "don't panic, just listen and we'll tell you everything" scenario rather than a "haha we got you now" hostage moment. Greys don't usually take hostages, and they generally don't prolong things.I could see this being a swerve situation in that the ghosts aren't the bad guys. There wasn't any bad smell coming from either encounter last episode.
