They get her drunk

 Patrick pulled out a flask from his back pocket and tipped it into her drink.  It was about two shots worth of straight Everclear.  He took a small swig and screwed the cap back on.  Dani wandered back to the table to get her drink.  Cynthia was leaning on Greg, the two of them passing the joint back and forth to one another.  

Patrick looked up at her, and said, "Hey, you want a shot of Everclear in that? We're out of Vodka." Dani frowned. That meant that the only booze left was beer, and she hated beer.

   "Yeah, sure." she said, holding out her cup with a sigh.  "Patrick is cute" she thought.  
   "Too bad he's gay."  She smiled a bit as he poured the shot.  

   "Say when." he said with a stoner's chuckle.  She watched the liquid pour into the cup, and called it after about 2 and 1/2 shots.  

   "Thanks." she said, and sipped it.  She scrunched up her face.  It tasted way too strong for her liking.  She wafted her mouth as the three on the couch started cheezing from the weed.  Dani chuckled too, sat the drink down, and wandered into the kitchen to find the last of the Pomegranite juice.  Patrick poured another shot into her cup, and barely hid it in time as she came back into the room.  She filled the cup up with juice, drank a mouthful, and filled it up again.  

Finally satisfied that it didn't taste too horrible to drink, she wandered around, sipping on the cup as they finished the joint. She was getting a little wobbly, but then again, she reminded herself, that it was only three shots in the cup, and that it would be last drink for her this evening.

   By the time they were finished with the joint, she had drank over half the glass.  She stumbled slightly as she sat back down on the couch, the **** taking effect very quickly...
