Ari Margolis, the man who creates the Fringe trailers, has been teasing tonight's Fringe season finale episode "The Day We Died" on Twitter:

Verbal Tease #1 "Bright orbs moving past... flaring... and as they come into focus, we realize we’re in--"

Verbal Tease #2 "Not only can I not tell you how the thing works, according to all the readings it shouldn’t be working at all."

Verbal Tease #3 "Our fate was sealed long ago."

Verbal Tease #4 "We finally get to see one."

Verbal Tease #5 "Peter Bishop, 47 years old, shrapnel wound in the abdomen."

Verbal Tease #6 "You think now is the time?" "I think it might be past time."
