Mark knew it was going to happen eventually; he knew it was only a matter of time before he ran into Elizabeth after the two had swapped bodies. And to make matter worse, he was going to be stuck in an elevator with her, for what he was sure was going to be a long and uncomfortable ride down from the thirtieth floor. Except she didn't yell at him or blame him like he expected. She just sort of stood there and smirked while looking at him, like she knew something he didn't. He wanted to ask if she knew more about the body swap, but he couldn't seem to bring himself to do so.
