1. Shredder never had a wife yet.

2. In most topics I read, Tang Shen died and Miwa disappeared, not died on the fire. Splinter thought that Miwa is dead.

3. In Karai's Vendetta, Karai said she lost her mom too when April said that she lost her mom. This heavily hints that she is Miwa.

4. Splinter said Miwa should have been 16 by now when she's alive. Karai is also 16.

That's the only stuff I know. We'll just have to find out if Nick will ever show an episode about the truth. Right now, we'll be patiently waiting until then.

anther reason :

the eye color of karai and splinter are the same
