Bruce nodded at Steve. The soldier was correct, even if he didn't understand it.
"We are all still saving the world. Just in a different reality. It's like the City got us from exactly the moments in time that it felt was necessary."
The scientist turned and left the room for a moment. A search of the pantry yielded what he was looking for. A small can of black olives. He opened and drained the can into the sink, bringing back only four of the sliced black olives.
He held up a slice for Thor to see clearly, "This represent us." He set all four olives on the half pizza in one of the boxes. The other box held a whole pizza. Each of the slices in he half box got an olive, "These slices represent the planes of reality."
Bruce plucked only one olive from the half box and placed it on a slice from the whole box, then looked up at Thor. "That piece is the City. The slices in the first box show that we are still there and fighting. Except for this slice here, in the second box," Bruce pointed at the only slice with an olive on it in the second box with the whole pizza. All of the other slices were sans olive, "This is us now." The olive was all by itself.
"We are in this reality together. We have to make the best of it until we can figure out a way to return to our timelines. Tony might be able to help."
