Without a doubt, the person they were both looking at was Jade. Zain and Skittle knew her well, and there were many reasons for that. One of them was the fact that she had come from their university, and not only that, but she was treated as a type of goddess among the boys.
For whatever reason that was, it was hard to imagine her being seen so well in their eyes because both of them still had clear memories of what she had done when the whole zombie outbreak had begun.
At the time, she was on the same dormitory floor as the others. On the reception floor, she was with Buke and Skittle, trying to wait for Zain to find a way for them to escape. However, it didn't take long for them to see Jade's dark side. She had tripped the fire alarm, causing all of the zombies in the area to head towards their building. Using that as a distraction, she was able to escape while leaving the other two for dead.
