"It's sitting right there on the cabinet behind you", Jon said, pointing with his free hand, Karyn currently occupied his other.
Emily turned around; on the middle shelf of the cabinet was the stone, just where Jon left it. She pointed at it, "That old piece of rock is a wishing stone?" she asked.
"Yup", Jon replied, "That's the one. I put a perception wish on it long ago so that anyone who saw it would react like you did just then"
Emily stood up and looked at the stone; she was pretty close to the display cabinet, turning to Jon, she asked, "Can I touch it?"
"Sure", Jon replied.
Emily opened the cabinet gently and removed the stone from its resting place. She looked it over, turning it over in her hands, and "Looks like an ordinary rock to me"
"I'll prove it to you", Jon said, holding up Emily's coffee cup, "Try to change this into something else"
"The cup or the contents?" Emily replied.
"Not really fussed either way"
"Ok", Emily spoke, she thought aloud, "I wish that the coffee in this cup was really iced tea"
The rock in Emily's hands started to glow; she nearly dropped it in surprised. After a second, the glow faded. Emily took the cup from Jon's hand and sniffed the contents; she cautiously took a sip from the cup.
"Oh my god", Emily said in shock.
"Yea, I know, pretty cool huh?" Jon replied.
"No", Emily said firmly.
"No?!" Jon and Karyn replied in shock.
Emily held the cup up to them, "This is the worst cup of iced tea I've ever had. Tastes like fish oil!" she said, adding almost offhandedly, "Oh, but the wishing thing is cool though"
Jon and Karyn laughed, Emily was the same as ever.
She flipped the stone over in her hands, "So, you guys ever play with this thing?" she asked innocently.
"Naw, not really", Jon replied, "We've been a little too busy, not to mention that we've got all that we wanted, so there's no need for it anymore"
Karyn nodded in agreement with Jon.
"So, do you mind if I " Emily asked, gesturing to the rock.
Jon smiled, "Keep it", he said.
Emily's eyes brightened up, "Really? You mean it? I mean this thing has the power to change reality as we know it, and you're just giving it to me?" she asked.
"Yea, just remember two things", Jon replied, "Wishes can't be reversed and it has a range of 3 miles. Besides, I'll always know where the stone is regardless, so if I really need it, i'll find it again"
Emily looked at the stone, confused, "Hang on, 3 miles? How come everyone still sees you as a guy even though you look like a girl and still see Karyn as a girl even though she only has a penis?"
Karyn shrugged, "Don't ask, don't tell, really. As far as we can tell, the swap wish that no one would notice seems to affect everyone we or Sarah comes into contact with, we figure its part of the way Jon worded the wish. Almost like we have our own perception filters on us"
"Hahaha, Doctor Who is funny", Emily replied, "I'll miss Tennant though", going completely off topic.
Jon, Karyn and Emily broken down into conversation that navigated away from the stone, she left it on the tabletop as they talked and talked for hours on end, revelling in new and old memories alike.
