Let’s watch the trailer of “Making Angels”, the next episode of the sci-fi TV series Fringe:

Fringe S04E11 Making Angels
“Astrid gets an unexpected visit from her Alternate, while Peter and Olivia track a killer using a toxin that has yet to be invented. Both universes collide in a case that pushes the boundaries of what is possible.”

Just thinking, would be great if there was some romance between Walter and Astrid.
