The girl gave him a friendly smile when he said that he too was glad to see that someone else was here. However, her smile disappeared when he mentioned what happened to him, how he too remembered going to the gates before he blacked out. She nodded in response to his question and she answered "Yes! That's the last thing I remember as well. I'm guessing you woke up in a classroom as well then," 

So this was Sky's Peak Academy? She had to admit, she had imagined the place to be brighter and full of students and faculty, when instead it seemed dark (with the exception of the overhead ceiling lights), and abandoned. 

She looked to the boy and she came to realize something. She said to him out loud "Oh! That's right! I haven't introduced myself!" She then greeted "I-I'm Cecelia Greene. What's your name?" She also wondered if he had seen anyone else in the school so far, but she didn't ask the question, and instead waited for him to introduce himself. For now, it would be best if she knew who she was talking to.
