And third, the real retromutagen that Donnie made will cure karai. Explain to me how Stockman would have gotten a hold of April's DNA, and it could have been a prototype sample of retromutagen he may have been working on. (Donnie did state that it takes ten canisters of mutagen to create it, and Shredder has a big supply of mutagen)

Also, what would Stockman need human DNA for during that part of "Vengeance is Mine"? And where would he have gotten it from?
