Please answer the following question: Who is Daniel's brother dating?  Answer the above question based on the context below:  Two men named Ty and Vachel are hunting in a forest and come across an abandoned church, which they go in to explore. After Ty sees their truck being crashed into a tree, Vachel is stabbed with a serrated machete by a chuckling assailant who then dons Vachel's hat and jacket. Ty, seeing the murderer come out of the church, quietly flees off into the forest. Meanwhile, forest ranger Roy McLean is at his home, where he encounters a van of five college-aged adults heading to rural property which one of them has inherited. Despite his insistence that they not venture up the mountain, the five continue along. Among them are Warren; his girlfriend Constance; Jonathan, and his girlfriend, Megan; and Daniel, Jonathan's brother. On their way up the mountain, they hit a deer, and encounter Ty stumbling through the woods on his way down the mountain; they dismiss his warnings of "demons," as he is visibly drunk. After reaching a point where the van cannot drive any further, the group set out on foot and make a campsite; at night, while around the fire, Constance, Megan, and Daniel hear noises around them and become frightened, only to find that Jonathan and Warren are playing a joke on them. The next morning, they hike along Silver Creek to a waterfall, where they see a young girl named Merry Cat Logan singing before noticing their presence and running into the woods. Megan and Jonathan go skinny dipping at the bottom of the falls, unaware that someone else has entered the water. Megan feels hands touching her and assumes it's Jonathan, until she sees him on shore, whereupon she panics and swims to safety.
A:
Megan
