TSNR - Master Susie

Based off a little idea a dude names gave me. Here is his original concept: fav.me/db9k6kv.

His idea was that rather than make an original character to fill the role of Splinter, Susie could join the party as a representation of Master Splinter. It made sense in many ways. Susie is older than the babies (and maybe Angelica) and is very trustworthy, so of course she would be a good Splinter. Also, Splinter and Shredder always have a history behind them. So does Angie and Susie. So, yeah.
I guess my only problem is that Susie normally isn't with the baby brood in the original series. Heck, it was only later on that she started mingling more with Angelica. And Splinter was a stay-at-home character who was always there when the Turtles needed him. Susie isn't always there, and even when she is with the babies, she's usually just with one or two of them. So yeah, not enough interaction to be an effective Splinter.
So, I guess that when she IS there, she'll do what she can when she can. Normally, she'll just sit in a corner or near the babies with her legs crossed and her eyes closed. And while she's not much of a fighter, she knows Angelica more than anybody so she has her ways of conning a victory out of her.

SO, how did I do?
