“'The mouse came back to life because Marie was the mouse the whole time!'
"How does that make sense? Marie is actually a shape-shifter, though she does so unconsciously, and has not, to date, remembered any of her transformations. Casey is an alien from a very, very distant galaxy who was sent here to study our planet, who also has (much less powerful) shapeshifting abilities. The mouse came about when Marie changed into a blob-creature and then changed back. While transformed, a bit of her dripped off onto the carpet, and was, unbeknownst to either of them, still alive. Casey figured out that this fragment of Marie was alive when a mouse touched it and the bit of Marie turned into a copy of the mouse. That was a bit of a giveaway. He tried to catch the Marie-mouse, but failed. After a while, though, he came into possession of the deceased remains of Marie-Mouse. He knew it was her because of alien shape-shifting-detection powers that make total sense. Reviving the Marie-mouse required contact with some part of Marie that was still living. He ended up getting a bit of her blood when she got a papercut. He revived the mouse, gave it a tracking device (an ALIEN tracking device) and set it free, hoping to gain a deeper understanding of Marie’s transformative abilities. The mouse has mostly just run around since then, though.
"Incidentally, Marie’s transformative powers are also the reason she can create fires. Her transformative abilities regard fire elementals as perfectly legitimate creatures. And, finally, she doesn’t have to transform all the way, duh. Just a little fire elemental will go a long way."That entry...is simply sublime.
