Levin seems to be an incredibly bipolar character. He bounces from elation and pure bliss to despair and depression almost instantly, with the tiniest of conflicts tipping him one way or another. While reading about his emotional swings, on one hand I sympathize with his feelings--he usually seems to have a (at least partially) legitimate reason for being upset, but he always lets himself dramatize the situation in his head until he is no longer upset by a real event but rather an escalated, dramatized version of the event that he created in his head.
Reading this, I wonder where this is going. Is he going to snap? Frankly, I was surprised that everyone made it through that hunting expedition alive. I was half expecting him to kill Veslovsky. Do you think that Levin will lose his temper and do something stupid? Or do you think he will gain control of his emotions and pull himself together eventually?
Additionally, I wonder why Tolstoy makes Levin, the character that transparently represents Tolstoy himself, this crazy. So far, I think Levin is the only character in this book that is so utterly ridiculous that I can't picture his character as a real person. It seems strange that his character is so unbelievable when he is actually the character who is clearly modeled after a real person.
