The document provides a detailed textual analysis of an EastEnders trailer focusing on Kat and Alfie. It analyzes both verbal codes like dialogue and sound effects, and non-verbal codes like costumes, lighting, and facial expressions. Key points analyzed include Kat's dominance shown through her boots and costume, the ominous tone set by silence and tumbleweed, and the tension in Alfie and Kat's relationship shown through their dark costumes. The analysis also discusses technical codes like shots, camera angles, and editing that build drama and signify an upcoming confrontation. However, the document does not provide the promised analysis of a second Skins trailer for comparison.
