Walter is drinking while Keyes is talking to him because he is trying to hide the fact that he is nervous and scared that he will find out what he has done.  Keyes came to Walters apartment to discuss with him about the case. Keyes is upset and is in clear pain. Walter has the door open to make Keyes feel welcomed even though Phyllis is behind the door hiding from the scam they are pulling off.  Walter is placed right in the center of the shot to show his importance to the scene and the fact that the characters are layered also proves his importance of being in the center.  From the view of Keyes, it is a normal conversation between him and Walter, but from the audiences view we can see Phyllis hiding behind the door, which adds suspense and drama.  All the important elements of this scene are placed on the thirds. All of the characters are placed on the thirds along with small details such as Walter drinking the alcohol and Phyllis holding the door.  Walter is in direct contact and view of Keyes because they work so closely and trust each other. On the other hand, Phyllis is behind the door not in view of Walter because she is sneaky and can’t be seen with each other.  Walter is dressed in his work attire because he doesn’t want to seem out of place or make Keyes suspicious.  Phyllis is dressed in all black because she is dark and sneaky and going to mess up the plan.  In terms of lighting, Keyes’ face is lit up as well has Walter because they are the ones having the conversation while Phyllis is just looming there all dark and spooky looking.
