Lol doesn't matter since the turtles saved the planet with time travel anyway.

I'm personally opposed to the Neutrino being an entire race of aliens like they apparently are. When I was younger I thought the Neutrinos were just the 3 teens we saw. I forgot about Tribble which implies there are more of them. But still I like the idea of April being half human, half space elf. It's an interesting backstory and you could even write her out if you wanted to by having her leave earth to learn of her heritage.
