That is the only explanation for this shot. Although I appreciate Shelley really going for full-on horror, as this is a moment wherein the Anonymous Hottie was about to call HNW a pig (he called her drunk and propositioned her; earlier in the evening, he'd called her sister. I just remembered that HNW spent most of the evening in a Hangover-esque What Did I Do Last Night tizzy -- look Hart of Dixie is cute, but One Tree Hill did the Hangover homage like 4 years ago. Come on, you guys.)
