At 4.23, when Ted comes into Rebecca's office to give her biscuits, Rebecca's salad bowl disappears between shots.
At 18.30, the TV abbreviates Richmond to RICH. TV stations only use three letters so would use RIC.
Brighton wear blue and white striped shirts so would change their shirts for the game but would not use blue shorts as they would clash with Richmond's kit too. The yellow shirts and blue shorts kit was their second choice for the 20/21 season. In 21/22 season they wore an orange coloured outfit which would not clash.
The TV shows there are 3 minutes of added time in the first half but the referee blows the whistle after for half time after only 2 and a half minutes.
At 2.18, Colin approaches Isaac and says "Do you want to get a drink boyo?"
There are different cultures in Wales especially regarding the use of English but, on the whole, you would only call someone a boyo if you were being sarcastic or looking down upon someone. In these circumstances of reaching out, Colin would be more likely to say Isaac, skipper, captain, mate or bach.
The fan demonstrating before and after the goal with Isaac has a Northern accent. A small club like Richmond would most likely have local supporters.
