Wings of Cover is an area spell that lets you choose who is affected, as opposed to a targeted spell. Spell Turning does not affect it. The good news from a metagame standpoint is that none of my spells can be turned, so at least the fact that I know about it doesn't cause a problem.
I was always unclear on one thing about grappling: can the Dragon try to do damage right now, or is that a separate check it has to make later?
Once these things are resolved, it is your turn.
