explain - 'good luck to you trevelyan, and may you get the petunias for your princess!
When John gets down at Coketown to get Petunias for his wife Jesse, the narrator comments, "Good-luck to you, Trevelyan, and may you get the petunias for your princess". The narrator's tone was sarcastic. For he addressed Pescud as Trevelyan, the hero of one of the best sellers and called his wife his "princess". The narrator commented so probably to remind Pescud of the fact that despite being so critical of the best sellers, his own love story was a fantastic one.
