catpixels: absolutely random question, has any of the curse victims ever end up with the knack of size shifting?
Phoenix: that would be cool!
nightmares06: Nope!
nightmares06: Knacks can’t change their size anymore than standard spellwork can
nightmares06: And changing the makeup of matter is something too strong for them
nightmares06: There’s a few stronger knacks out there than the usual psychic abilities, but nothing along those lines

The visions are from when I first started writing the series, and they’ve been phased out in lieu of Sam’s knack. I found his new ability (and Dean’s, when he’s small), to be more fitting to the series as a whole.

Dean can find whatever he seeks and Sam knows when he is sought.

A fitting pair.
