When Eric swapped bodies with his co-worker, Angie, she kept threatening that she was going to do something weird to his body, like getting a face tattoo or an odd piercing. Eric kept warning her not to, but he couldn't seem any sort of equal threat on his end to keep her in line. That is, until he told her he'd cut off all of her hair. She finally agreed to behave until they could find a way back to normal. In fact, any time she got out of line or said something that would be uncharacteristic of him, Eric would reach down to the desk and pull up the scissors. He'd then give Angie a look; she'd quickly quiet down.
Carl hadn't given much thought to the storm outside. He was more concerned about the job interview he was heading into. Of course, when he encountered a woman in the elevator, he let himself relax for a few moments in order to hit on her. She rebuked his advances, but when a lightning bolt struck, she jumped into his arms scared. The lightning bolt and the pair's proximity did something else quite strange as well -- it merged the bodies of the two into one! Mentally, Carl felt like he was still in control. He still had his blond hair as well. However, he was certainly a woman now; he had her figure. And he felt a little disgusted with himself for hitting on the woman just a moment ago (he guessed he got that from her). Then he began to worry about his job interview; how was he going to go looking like this?
When Heather told Frank that she had no idea how they had switched bodies and no clue how to switch them back, Frank became furious. He was sure she was lying and slapped her right across the face. Heather didn't react much; she just kept up the lie that she knew nothing about how they swapped bodies.
Before the Great Shift, Lester had been frequently stressed out, but swapping bodies with a woman certainly helped his psyche. In fact, it was now so easy for him to find himself in a peaceful place. He just needed some way to shake the curve of his new body. Dancing was fun at first, but hula hooping seemed like a better option these days. He just let his hips go back and forth, back and forth. Soon enough, he found himself in a better mood.
