More about the character:

Liam is an alumnus of the school who visits occasionally to help the teachers and principle prepare events. He appears every so often for the first few episodes, but then, later on, becomes a supporting character (he is listed as a minor character for now). His younger sister (who has no real role in the series' storyline) is the reason why he visits. He eventually becomes the assistant of Malia's homeroom teacher. As he moves along with the flow of the school, he begins to be suspicious of Malia and her friend group - there's something about her that is different from normal students.

There is not much to say about his past is that it seems fairly normal, though Liam has a night-time side job that is a big mystery to the students at the school. Some believe that he is a private investigator, while some think he is a model because of how handsome he is. But, his job is far more shocking - mainly to Malia.

His behavior is usually calm, he's average in the sense of his moods. He's not one to be overbearing and stays neutral the majority of the class. There are times he teases students, mainly Malia and Chrissy, but he's pretty much always doing work.

He's German and has black hair and brown eyes. Also, he's probably in his mid to early 20's.
