I just happen to read that in this series, Leo is younger than Raph and Donnie (http://turtlepedia.wikia.com/wiki/Teenage_Mutant_Ninja_Turtles_(2012_TV_series)) When did that happen?? In the released episodes isn't mentionated the turtles' order; so, how can we know is truth? Do you feel Leo is younger that Donnie and Raph? Maybe that could explain all that Space Heroes thing.
