User blog comment:MrAnonymous/I felt so bad for Adalind/@comment-2255188-20120416073105/@comment-108.34.42.71-20120417033402

I have a different theory. My theory is that Wesen have a human half and a creature half, two halves of one soul. When a Wesen ingests the blood of a Grimm it kills the creature half while leaving the human half untouched. This would explain why a ghostly Hexenbiest came out of Adalind after she accidently drank Nick's blood, and why the blood turned her into a human. Also i don't think Adalind is going to for give Nick any time soon. Adalind had unreturned feelings for Renard, and as a result was trying to impress him hoping he would one day return her feelings. Now that Adadlind is human Renard has no more use for her and thus it is now impossible for Adalind to earn Renards's effections. Adalind also stikes me as the type that holds a grudge like a Siegbarste, so i expect Adalind will be back with a vengance sooner or later.
