Syndi Losstarot, Little Sister of the Dark

This is why people have to learn not to make typos around me. I've seen the "d" and "n" accidentally transposed too many times now... and so therefore, Sydney acquired a long-lost little sister.
...Yes, I was bored.
It was driving me nuts, because she reminded me very much of someone, but I couldn't figure out who for hours... then it hit me: Deedee, from Dexter's Lab. O_o

Syndi: Oooooooh! What does this grimoire do?
Sydney: Syndi! Don't you dare-
*lightning strikes him*
Syndi: Cooooool! I made lightning! *dances away happily*
Sydney: *coughs a puff of smoke* One of these days, I fear she will kill me... Even if I am immortal, I think she just may be able to manage it.
