Impressive view into Splinter/Yoshi.
What do you make of the point where he moved from one identity to another?

Wow. I really enjoyed this. Splinter is totally believable here, and the image of Mikey playing with his tail and giggling, plus the agony and joy it probably brought to Splinter...So cute!

I like the touch of anger at the end, the conflict between killing and just trying to lay low. And Raph totally would stab himself. Really good job with the fic.
