Alice gave up on trying to prepare for another attack from the demon and went back to floating on her back again. While Xander might not have been losing his mind yet, but she was pretty damn close to it. She had already hit that point in drunkenness where she wasn't afraid to sing or dance in front of people and she was definitely singing out loud now as she closed her eyes and floated there. It probably wasn't the best idea to let your eyes close while you were in the ocean, but she was really starting to feel dizzy now and closing her eyes helped. For a moment she had almost forgotten that she wasn't the only one in the water.
Then that splashing had brought her back to her senses slightly and she was able to take a deep breath before she was pulled back in. Instead of fighting and trying to get away, Alice let herself get pulled in this time. It might have been dark and although her vision was already hazy from her current state of mind, she was able to make out Xander's face as she opened her eyes and she did her best to smile at him underwater.
