Ok, we've seen Harry and Thomas, and then in White Night Ramirez and Lara.
So it's well established that you can soulgaze a full White Court vampire.
Have we ever seen or heard of a soulgaze with a Red Court? (And Susan doesn't count on two factors.)
Or Black Court for that matter?
And we can leave out the sticky "Why would you WANT to?" question.
Doesn't this imply that White Court are still, on some spiritual level, Human?
And as such, wouldn't the Laws count? (Barring a "vampire exception" clause?)
Could you soulgaze a Changling? (Not fully farie yet?)
