Y'all know Stephen Graham is mixed race right... Soooo....
This will be brought up to why he has such hatred towards black people. We see him look at the pic of his heritage where his father is black. My guess is after milky and his Uncs seriously smashed up combo, milky will will regret and take him to hospital where combo will proceed to tell him he was abandoned by his father and was jealous that milky was kept and adored.
Think Sean might get involved somehow aswell, banjo coming back I reckon he might be killed
