There was no gender separation between male and female, at least not in the researchers' dormitory. So, by choice, Luke and Meredith stayed in the same room.
The reason Luke and Meredith were in the same room was simple.
The two didn't know anyone else at the academy, even with Hazor's recommendation and the time spent alongside Zhanid, the two still didn't completely trust him. So the most logical decision was to stay close to each other.
At first Luke was wary of this option, which was proposed by Meredith. But he soon accepted because he understood these reasons. After that brief conversation between the two, Adrian guided the couple to a spare room in the dorm.
Entering the researcher's dormitory area, it was possible to see a marble floor and the structure finishes in a white stone and oak wood. The place was lush and appeared to be quite large. However, it still wasn't as surprising as the Strogueher mansions.
