I know they look simalar but has'nt Pen Ward stated that they are not the same person?I mean spmetimes they can have a trick or two up their sleve but come on!I do not think they would lie about this.Most likely they will make a completely new charecter when or if she ever is seen again.I know they both wear lab coats but doesnt dr.Ice cream and so does Finn in a episode.But no one is speculating them....and I know....OMG! they have the same parasite thing on them but so does Dr. dextros Simon and Finn seems to have that one when he wears the coat.So please all speculations aside why are they similar in any way?
