Thor was somewhat startled by the appearance of his sister-in-law. Which was understandable, given that Jessica Rabbit was showing a lot of very pretty, smooth, caramel-colored skin.
So when Sif's name came up, it was like a bolt out of the blue. And it hit him square in the chest. For a second, Thor forgot to breathe, and when he finally remembered, the darkness almost immediately started creeping into his brain.
He shook his head, trying to dislodge it before it could take root. Not now. Not here. Please, not here.
"I need a drink," he muttered, and turned heading toward where he vaguely remembered the bar being. Wasn't there an exit near there? Maybe he could just get out before anything bad happened.
