Thanks for the answers! I've read it through, so I knew Alopex was earlier with them but I wasn't sure how much had she had been along with them.(I don't actually know that much about Alopex, I still gotta catch up to IDW Turtles)
I didn't notice Artie on the final battle with Shredder, my bad
So Artie is their blood sister, or you're going "the Next Mutation" route were none of them are actually blood related?
Anyways, great work! I'll await for the following pages eagerly .
