The final shot of the trailer is a wide shot of the main female character stood on a train platform, the shot shows a train going past to reveal the female character stood facing the camera. She is positioned to the far right showing that she had been weakened as she is not the center focus anymore. She is stood up straight, emotionless denoting her looking slightly sinister portraying the narrative as having psychological damage on her, giving it a twisted feel to it. 

A second editing technique used throughout the trailer is fade to blacks, the colour black has connotations of darkness which relates to the thriller narrative that the trailer contains. Another use for the fades are to denote a passing of time, so it could show that the film is set over a long period of time - maybe the disappearance of the woman was a while before the present setting of the film, possibly meaning something (or someone) in the present has done something to bring back this narrative. The fade to black are also used in particular to denote endings to certain sections of the narrative so that the trailer can progress onto a new section of the narrative. This is a common convention within the thriller genre  because it is effective in making the audience unsure as to what is going to come next. 

The trailer is edited in a montage layout, where the scenes are not in chronological order. The enabels the audience to gain relationships between the different characters while also experiencing the main parts of the narrative as well. This also helps the trailer to not give away too much of the narrative so that the audience would have a brief idea, with some gaps (which they would fill when watching the whole film). This is shown around 1 minute 16 where a shot of a male and female character in a car with one another fading into a shot of a train track, the frequent feature of trains within the trailer hint that they are a significant part of the narrative as they feature in the titles and trailer itself. 

In order to show the vulnerability of the main female character, a close up shot of her face is used. This is very conventional within the genre because the close up shot  can help to express the emotions of that character to the audience, allowing the to feel more engaged with the situations of the characters when watching. 

When representing one of the female characters as being secretive, an over the shoulder is used to highlight her daily activities. However the over the shoulder shot is interrupted by a  group of people looking at the female character. The shot is blurry to begin with then focuses to show 4 females looking at the character, the narrative gives no hint as to why they would do this meaning that this character is very important to the plot. The over-the-shoulder shot can also show that she could be hiding her identity, as we see more of her actions rather than herself, which could also relate to her being a very secretive character. The blurred shot represents the females life not being as clear as the audience might think, denoting that she might be a surprise to the audience in the future.
