Looking at Wanda in page 2, comparing with Wanda in page 160, I reach to the conclusion that it changed from an "infantile" aspect to a more adult one.
I ask myself:
* Does this reflect unintentional changes in the POV of the authors?
* Was this intentional, trying to reflect a possible change in the reader's way to look at the comic as the story advances?
PS: It does not only affect Wanda. For example Prince Ansom, page 7 and page 158.
