Arabic writing
The Arabic writing is الميادين , 'almayadin', which seems to mean 'fields'; the writing is associated with a filled dot directly below it. This refers to the red-edged football field/goalpost hex which it corresponds to (when the solved hexagonal grid is matched up with the thumbnails map). The field is the football ground at Camp Nou (translation: new field), home stadium for FC Barcelona, which is Lionel Messi's team; the image is from a game where he scored a hat trick against Espanyol in September 2017. Similarly, the AK-47 on Page 11 corresponds to the blue-edged hex of Messi.
From the Hexagonal Grid solution, we know that this Camp Nou goalpost hex with all-red edges is the ending point for the Match of the Day musical code.
Grey dashed lines
The first grey dashed line links the hexagon containing a rainbow-coloured xylophone to the thick, grey edge of the hexagon-containing grid. The second connects the grid of letters on Page 6 to the hexagon here containing Jeanne Loriod (next to which is a small mine/key symbol). See Grey Dashed Lines.
