Nick and Jay (and Daisy)

Tsk, tsk, tsk, a love triangle... (kinda)
  
I must say, I was REALLY surprised in chapter 4 when I read that Daisy and Gatsby were lovers a while back. I would have never expected it, but hey, that's the magic of reading, right?

Right?

Jay is CLEARLY very nervous of whether Nick agrees to invite Daisy over to Gatsby's mansion, so he does all these things for Nick, such as take him to Coney Island, and for a swim in his pool, and even hiring someone to cut Nick's grass for him. I feel that Jay is kind of using Nick as a calming effect... or whatever. I don't really know how to explain it, but I guess what I'm trying to say is that Jay often feels better if anything he does, concerning Daisy, is okay-ed or approved by Nick.

Having read chapter 4, I knew that Jay had some feelings for her, but now, it's like he's CRAZY for her, like he malfunctions and the sound of her name. Jeez!
