It seems so weird to Barry to be back in the world. To be under a real sun - blazing hot though it may be - to breathe the polluted air of the industrial age, to see a city and so many people.

Normally, he would hate being in a car. Especially in the traffic. But he feels strangely comfortable. The world is out there. They are in here. At some level he knows that this world - or the one that he came from, so much like this one - is not his anymore. Oh, he can leave sometimes, but in the end, he can't stay. And yet Sara knows this, and still loves him. He smiles.

"What's with the smile?" she asks not far from the lab.

"Oh, nothing," he says as the smile gets bigger. He is sure he doesn't need to tell her.

Arriving at the lab, Barry feels at home immediately. The smells are less intense that he recalls in the blast of the air conditioner, but they are those of his life. Someplace here there are forensics. Someplace here there is justice.

But someplace here there is also a budget. "Wow. Nice place."
