Walt's Wonderful Watch

For one reason or another, now Walt can see extradimensional and supernatural stuffs. What he can see is rather vague on purpose. Is there something from your canon that he can see? Or does he see "something" when he see you? For example, maybe you actually stash your weapons and mech in another dimension. Or you transform to another form to battle, where does all that mass and matters came from? Maybe he can see weird colours emanating from your mech when it does its special attack. Or maybe something as simple as supernatural aura emanating from your body. If you think Walt should be able to see something from your canon, post your ideas here! Or PM/AIM me if it's supposed to be secret, I guess.
