Didnt seem all that excited to see greer, who in their mind died back on the planet. You would expect them to show a little surprise when they talked to him, but its like they expected him to be alive or something? Especially the way chloe talks to greer and says " what do u mean u werent expecting to see us, didnt u guys figure out a way for us to dial in?" This is definately not the first thing that comes out of ur mouth when talking to some1 who seconds ago u thought was dead and u abandoned him on a planet. I mean didnt he get a oh my god ur alive im so sorry we left u on the planet, oh by the way how did u urself get back to the ship?
