I was thinking the same thing, but maybe I didn't understand the timeline? Did Logan sleep over the night after Shelly's party? Because it seemed a little off to me that Veronica would be eyeing his junk and teasing him about it just one day after being raped.

However, I do like the switch in what happened between them--that everything happened the same way until the salt lick, and then one moment of humanity from Logan completely changed their relationship from that point on. Very interesting.
