"Let's try swapping hair," Amy suggested. "That's something simple to start us off."
"Okay," Evan said. He was glad that Amy picked something simple to start. "I guess I just need to focus on making the swap?"
"If it actually works," Amy said, laughing.
"Let's find out." Evan focused, and suddenly he saw Amy's hair becoming shorter and darker, forming into his short brown hair. Meanwhile, Evan's own hair grew out and became lighter, forming into his girlfriend's long blonde ponytail.

Evan focused hard, and then their hair was back to normal. "Now what?" he asked.
"Well, let's try swapping something else now that we know it works," Amy said.

Amy sighed. "Alright, fine," she said. "Evan, tell her,"

"Wow, this is amazing!" Melanie said. She looked excited.
"Yup," Amy said as Evan reversed the swap again.
"Can I swap something?" Melanie asked.
"Depends on what it is," Evan said.
"Hmm," Melanie said. "I want ..."
