*head desk* yep, I wasn't paying enough attention... but I have way too much time on my hands, so I looked up break enchantment and now I noticed something interesting, if petrification can't be reversed by dispel magic, then break enchantment would not be able to undo flesh to stone. this is because flesh to stone is a 6th level spell and break enchantment can't reverse the effects of a spell level 6+ if the spell can't be undone by dispel magic... so we can conclude that flesh to stone can be countered by dispel magic and that V didn’t prepare it that day. We can also conclude that V has improved counter spell.
