Nicely done.

Twisted, sad, happy. Really well done

wow, it's the only thing I can say. It was so different and so incredible (in the good way)
Believe me, you almost made me cry.

This is so unbelievably cool! Please write at least one more chapter, I would really like to see Pepper's reaction to her AI daughter, and what said AI would be like.

Can you continue it?

Pretty good. Gimme a yell if you ever do more of this, 'kay?

Good plot. Will there be mode?

So sweet I hope you post more to this. ... I want to know what happens next :-D

This is great... I can't exactly find any words to describe this. I like your writing style, and I think you got all the characters down perfectly. A word of advice for any future works is to check over your work to look for any small errors in grammar or spelling. I didn't find any, but it never hurts to check.
Great job, and good luck with any future works!

I think you made Tony a mad scientist, but i like it XD
Though I wondered, if Tony could build an android, i think he should be able make Catherine appearance aging.

That's really strange, but like you pointed out, Tony would be capable of anything xDD

Really liked this.

Awesome! Looks like a great beginning. Why do you have it listed as completed?
