Also, kudos if you already realized that most of this post is just me messing around. :) A couple of those theories are actually really good! Joan Groady would get anything for a news story-- determined! And then there's also Bishop (old-time favourite character!)...if I remember right from the 2003 series, Bishop knew quite a lot about the Turtles BEFORE he actually met them, so...maybe Bishop'll want to experiment on them since he knows what they're like and everything.

There was also another one you mentioned in another comment: '"Splinter may be trapping his sons, anonymously and without warning, as some sort of grand training exercise". 'And I believe that was "Tales From the Turtle Lair" (or something like that, anyway ;) ). Now that would be a good plot, but unfortunately I don't think that's going to happen as it's already an official footage and everything :(                                                                                                            (BTW I know you said that pretty much every theory was "messing around" :) )
