Thirteen hours ago, Gillian Anderson posted a tweet: "You found the X!!! 10k RTs unlocks a glimpse of the truth!"
Hours later, when the counter was near the number, Fox replied: "YOU DID IT! You unlocked exclusive content! Go here: http://findthex.tumblr.com , password: XPhiles Good job!"
So, what was hiding there? New teaser called "Show & Not Tell", featuring Gillian Anderson, who said: "The X-Files is shrouded in mystery, and I can't really tell you very much about anything, really.
But I think I can show you this..."
Then, get one or two-seconds mixed with lots of still from six new episodes. "Cool, huh?", Gillian added.
