Well they sure did good in this episode & it keeps getting better, can't wait till March!
----------> Skye aka Daisy Johnson "Quake"... Raina aka Raina Earth-616... the Inhumans. As for Trip aka B.J. Brit, hard to say for a dead person that is rumored to be in Avengers: Age of Ultron & it has also been mentioned that Agents of Shield will lead into AoU like they did with Captain America.
I am also proud to be a part of this text flight by having my name on a dime-sized microchip & also will be on future exploration flights & missions to Mars. Damn! I have 60k in space thus far, starting to be like that Howard guy!
