She tries to get Lana in trouble

"Yeah, he'd like to hear about this," Mackenzie starts blabbering, "I saw this girl running through the haunted house butt naked. I asked her what she was doing and she said she was having fun and that I should join her. I said no, but she just pulled my dress off and grabbed my hand, leading me all over the place until we were lost."

"Mackenzie!" Lana is taken aback and shocked by the confidence with which Mackenzie was spewing these lies. "What are you doing?!"

"None of that is true," she turns towards the man and tries to explain herself, "I am not a streaker, and I am not naked on purpose. Everything went dark and some creep just took my clothes off, and then I ended up in some pool with this lady."

"Do you really believe her?" Mackenzie continues, "didn't you see us just now hugging? We were making out while the showers were closing in on us."

This was a step too far. Not only did Mackenzie initiate this making out, but this was sure not how Lana wanted her boyfriend to hear about her very likely cheating on him. This was starting to add to her panic that people were not only seeing her naked, but thinking she was a streaker and unfaithful as well.

"Oh, you bitch!" she yells at Mackenzie before turning back to the man, "This is all lies and whole cloth, you have to believe me. We were only cuddling for warmth and modesty..."

"Yeah, mm-hm," the man just keeps walking down the hall in front of the bickering ladies, not particularly buying either story but also getting too focused on the corridors to turn back behind him.

Eventually the three walk up to a waiting area where Lana's boyfriend and park representatives await them.
