Mary is about to finish the return bowl when she remembers something from high school biology. Certain creatures such as slugs have regenerative abilities. Mary had always wondered what it would be like to double something of yourself!
Mary stepped/slithered to the counter and grabbed a knife. Hoping this wouldn't hurt, she cut her finger in two. The test passed, with surprisingly little pain. Quickly she notices change; the finger almost immediately regenerates into two. This was going to be fun.
Now Mary wanted to try with something a bit more... eccentric. She gathered up the will, took a breath, and sliced quickly through her head. Immediately she blacks out.
Waking, Mary thinks, "That was the dumbest thing I've ever- What time is it?" "Whoa, I can't think str- what comes next?" "Wait I'm- did my 'operation' work?" "uugh my head..."
Mary gets up and walks/slithers herself to the bathroom, and nearly dalls over at what she sees. She sees a mirror image of herself, with two heads. "hmm.. I should try and control this- wonder if I sound different from my- -other head" "whoa. that was wierd." Not wasting any time, mary speaks, and two thoughts come out.
"this is wierd" "this is slimy"
"time for the return vial" "indeed, absolutely, yes,"
