I've seen a million posts go by on my FList and I didn't read them to avoid spoilers, but I really only have one comment.
It was only about halfway through the episode that it finally sank in that they've been trying to create sexual tension between Neal and Alex.
My head was so thoroughly absorbed with the true romantic conflict at the center of this show - Neal/Kate versus Neal/Peter - that it literally did not occur to me that the show was trying to suggest there was tension between Neal and Alex.
And then halfway through this episode I'm watching and I'm like - Oh! They were serious about that?
