[No this is not as planned at all. Her feelings about DiZ are still mixed and mostly negative but the idea that he did this not only doesn't make sense... it's also clearly escalating this situation in a way that was a bad idea.]

N-no, Axel that's not what I mean at all! I mean... if... if he'd done something, if I'd taken Roxas' memories or something like that- I-I'd know, wouldn't I?

[She's trying to explain this as calmly as she can. She's not entirely succeeding]

Axel he's shorter than me. I don't think DiZ could do that.

[Because Roxas had been a good inch or two taller than her back home.]

It's like... if time freezes while we're here, then we can go home and it's like we were never gone. It's like it really is him from back then.
