During his thirties, Walter explained the concepts of alternate realities to military officials and retrieved information of technological value.

After Peter's funeral, Walter witnesses his other self almost succeeding in creating a cure for his alternate son's illness and sees the Observer September arriving to witness the important moment.

Notable QuotesEdit

Walter: I've given him a name, Carla.
Carla: Hmm?
Walter: "Walternate."

Walter: The Casimir Effect should produce a thinner, more porous region of space-time. I only need to affect the area for long enough to cross over to the other side with the vial of the cure. And... and then, of course, recreate the effect to cross back again.
Carla: Walter, you're trying to create a wormhole into another universe?
Walter: Yes! I think I just said that.

Walter: It was the first hole, Olivia. The first breach. The first crack in a pattern of cracks, spaces between the worlds. And it's my fault.
