Another Peter has abilities thread

[itaintrite]

So I've been re-watching all of Fringe so far (cough * http://fringe-forum.com/forums/showthread.php?t=6618 * cough), and there's one thing from "Peter" that was interesting.

Peter seemed to know Walter wasn't his father (Walternate). How?

There are only 2 explanations.
1. He's a smart kid. He deducted it from Walter's strange behaviour... but seriously, is this possible? He's around 7. Walter looks exactly the same as Walternate. How could he have possibly known? And that leaves us with the only other explanation.
2. Peter could also identify objects from the other side. Meaning, he was also experimented on as a kid. (There are other "proofs" to back up this theory, the "magic touch" etc).

So, what do you think?

From a humanistic standpoint, maybe Peter thought it was weird seeing our Walter be so affectionate with him. Maybe Walternate wasn't as warm or affectionate as our Walter is. Not to mention, Walter's clothes (remember Alt!Liz questioned Walter on his clothes) were probably different than what "his" father is used to.

From a Fringe standpoint, it is weird seeing Peter pick up so quickly that our Walter was not his father despite them looking exactly the same. So yeah, let's hope the season finale will finally answer the question on why Peter is so special.

Yes, no 7-year-old is that perceptive. Imagine yourself as young Peter... freezing your butt off. Would you question the man who looked/talked exactly like your father?
