Just like a sheep caught in a wolf's den, Marissa sat down opposite of where Giovanni was having the best time of his life. For a second, she had to ask herself what her aim been here was, and she couldn't get any reasonable answer, because the man who was the reason why she wanted to be here in the club was having a good time with the two strippers besides him, while she sat like a total klutz not knowing what to do.
Maybe it was right that she leaves, but that was like embarrassing herself. She wanted to be here in the first place, but right now maybe being down there, drinking and chatting with Joel might have been much better than being ignored, and treated like he didn't come through for her moments ago, when he allowed the security to let her in.
