Fox has finally released the Fringe 5×01 promo, and it’ll blow your mind! Watch a brief glimpse of what appears to be the moment which breaks up the Bishop family.

The promo shows Olivia, Peter and a young Etta in the park, but the Observers appear and Peter desperately calls Etta to him. But we’re thinking that this may be the moment which separates the family for a long, long time. Did anyone else get chills watching this?!

The first episode of season 5 is called “Transilience Through Unifier Model-11,” and airs on September 28.
