The mysterious old man, who apparently was wearing a purple bath robe, opens a cabinet on the back wall and pulls out a little dusty flask of sorts. He puts the flask on the counter, right under Tom's nose, and makes a raspy chuckle. "What is this? Some kinda antique herbal medicine or something?" Tom asks, puzzled but not very impressed. The old man points up his gnarly index finger dramatically. "It is no such thing, my lad! What I have for you here is a very potent magic potion!" He smiles a crazed, yellow toothed smile seeing Tom scratching his brow in disbelief. "Hm ok then. Say I believe you, but still, what does it do? How will this help me with my thing?" The old magic man's face quickly goes serious. "I shall explain now, so take heed, lad! This potion is not something to take lightly, or to handle without caution. It has a great and terrible effect! One must simply pour it into the desired person's drink, and as soon as he, or she, swallows it, the magic begins. The body of this person will become empty, hollowed out, and drape to the floor as if it were garment! Hah!"
Tom raises an eyebrow. "So, why would I want something like that?" The Wizard pokes his long, bony finger at Tom's chest. "What you desire, my lad, is to take the two people you mostly cherish, your girlfriend and your best friend, and to merge them. Two become one! This can be achieved by having one of them wear the skin of the other!" Tom goes wide eyed. "Whoa! That sounds wicked! But, question is who should be the wearer, and who should be worn?" The Wizard smiles. "I see you are now interested in my magic potion lad." "Well, hell yeah. Sounds crazy awesome, old man!"
The old man rubs his hands happily. "Excellent... I shall sell it to you for the bargain price of 9,99€ lad. It's a fair price, I would say." "Fair price? It's a real bargain old man. You got yourself a deal. Hell yeah!"
Tom pays the Wizard and he grabs the magic potion in a rush to leave and use it. The Wizard stops him. "Wait lad! Don't rush out, listen to me first... I cannot stress it enough how carefully these matters should be handled! Magic can be a dangerous thing and if misused, may have dire consequences which one might regret. Know that the potion must be drank in its entirety for the spell to ignite. Know also that the flask contains only one charge of the spell. If you wish to do it more than once, or even revert the spell, you shall have to come seek me out once more. Finally, as for who should wear who, well that is entirely up to you... You decide. Think well and choose wisely, so that you might not regret your decision." The Wizard finished off, giving Tom a stern glare. Tom just shook his head and said "Yeah, yeah, I got it!" before heading out of the magic store...
