Think of a way to take her to the place where the Dungeon is

When she woke up it was 2 pm, he was still next to her, she had been napping for 3 hours. He immediately started talking about where they could go, suggesting the lake where they could swim that they talked about online before. She agreed and said that she had a swimsuit, but first she needed some energy, so they both went down to the cafe of the hotel and ordered some milkshakes and food.

Then they were back to the room and as she was getting ready, she found it strange that he was just sitting there waiting, he didn't have any stuff with him to change, how was he going to swim ? In fact he left all his clothes in his backpack in the dungeon, and didn't consider the fact it would look suspicious if he was going to spend his time with her at the hotel, so he argued that he didn't want to so that he could help her carrying her stuff, and that he would go back to his apartment to get clothes later, and how he was already wearing his swimming shorts under his pants, which was a lie, but she didn't question his logic any further.

They were on their way to what she thought was going to be like swimming at the beach, she was excited, she was already starting to think about how to teach him to swim, and was getting more comfortable talking to him once she had something specific to discuss. But she didn't know the place, she never been to Canada, or anywhere for that matter, and had no idea that they were heading to where there wasn't a single drop of water in reality.

It was that exact same spot where he had been earlier in the day, he asked the cab to stop right there. They started walking into that forest and she was expecting to see a lake, but after walking for 10 mn she started asking if this lake was still really far away and if he was sure they were in the right place. He diverted her attention by interrupting her to announce that he had a "surprise" and wanted to show her something else first.

She followed him as he identified the tree with the "A" carved on it discretely, and started unrevealing that hatch again. "wtf is that ?" she asked, and confusion and anxiety had submerged her being as he opened it and invited her to take the ladder that was hanging in the dark hole. She took a step back with a blank expression on her face, as if she suddenly sensed something was off only at the sight of this strange hole in the ground, then another step back, and that's when he realized things weren't going to be that easy...
