In this extract, disability is represented quite stereo-typically. Character Billy has a mental disability and it's represented by many micro elements, one of which being, sound. There is use of diegetic dialogue by Billy when talking to Detective Frost and his dad. Billy speaks very calmly and gentle, he also uses very simplistic words and short sentences indicating that he's very childlike and therefore innocent.
Another use of micro element is editing, whilst Detective Frost questions Billy about where he was during the time his friend went missing, the editing techniques used signifies the importance of the conversation. Long takes were used to set a slow pace, calmer and relaxing scene. Billy, once again, reacts very slow and gentle, almost as if he was clueless to what was going on. We as viewers would feel sympathy for him as we'd agree that he was clueless and innocent.
Another micro element that was used was cinematography. This represented disability very well because of the clear camera shots that were used, for example: at the beginning of the extract we see Billy in the forest wandering around, there was a use of 'Over the shoulder shot' which made the viewers see police with flash lights looking for someone. Although Billy runs, he is outnumbered by the police and they caught him easily.
Mise-en-scene also helped represent disability in this extract as Billy had cuts and grazes all over his cheeks and forehead. This connotes that he as a character is someone who is very vulnerable and weak, he needs someone to be paying attention to him at all times so he doesn't get hurt. This invites audience to sympathies for Billy as he can't do much to help himself.
Another example of sound being represented by disability is how Billy raised his voice more and more when Detective Frost starts to suspect his suspicious behavior, he shouts "I wasn't with Trisha!" which made viewers see a different side of Billy. This connotes that Billy's getting impatient and annoyed at the accusations being made of him hurting Trisha.
The shot reverse shot was used in editing during the questioning, this helped viewers see the differences between Detective Frost and Billy. Billy first gave an impression of being innocent and gentle, although his attitude gradually heated up towards the end of the conversation. We can also see Detective Frost feeling frustrated of Billy's comebacks, denying that he was with Trisha even though there were witnesses that saw him with her.
Also, the body language in the use of mise-en-scene helped represent Billy's disability. At the beginning of the questioning when Detective Frost starts asking him laid back questions, Billy would answer them with confidence, however, once Detective Frost mentioned that there were witnesses who saw Billy with Trisha before she went missing, his body language switched to slightly more negative. He would avoid eye contact with Detective Frost keeping his eyes on the ground and starts getting fidgety. This allows the viewer to think suspiciously of Billy.
