I was not too excited by the previews to this one, and the comic is cool, but not earth shattering or anything.

Re: Snowbird shifting to mess up Kara, I think it works. It has been shown before that when Snowbird shifts, she becomes the animal so completely that she also takes on the animal thought processes, and is actually in danger of losing her humanity. Although, can Kara's pheromones affect animals? I thought they only worked on people...

Completely agree on Dr TwogoungmEn and the open heart surgery.

Reserving judgement on the Marrina recharacterization. She is acting like a rebellious teenager. Makes me wonder if she isn't really one of Marrina and Namors kids... :P
