Family relationships

• "He'll get on a lot better if you screw the heid, right?"

  Billy is blunt with Davie - stability, not uncertainty, will help Alec to thrive.
• "there's yer yacht. A blue and white it is!"

  Billy, unlike Davie, fulfils his promise to Alec.
• "...ah had a word wi that bookie."

  Again, we see Billy's decisiveness. He cares about his brother and does what he can to help.
• "Ma bursary money'll be comin through this week, can pay it wi that."

  In a role-reversal, Alec becomes like a supportive parent. He sacrifices the money that's supposed to support his education.
• "Think a came fae another planet."

  Davie articulates the distance he feels from his son. He feels his son's lack of respect for him, and knows that he is pushing away.
• "Look at the state ae us."

  Alec's frustration bubbles over. He feels disgusted by their hopeless situation.
• "Ach aye, yirra good boy son. Wallop"

  Davie slaps his son and Alec is indignant. The tension between the pair has built to this emotionally charged climax.
