There are maybe a few similarities between the two, but there is not nearly enough to come to that conclusion and it be correct. And they look nothing alike. Different hair color/style, he talks, he's wearing glasses, and he just doesn't look the same. And is it me, or is it kind of weird to have a guy with a version of himself from like 20 years ago right next to him. I get the feeling they would have said so if he was Crono.
