Stuck-Up Steve

Margaret and Stuck-Up Steve have rich guardians, but Steve's mother Rich Aunt Ruby is much richer than Margaret's parents. However, a difference between them in terms of wealth is that Margaret is ungrateful of what she has most of the time, and doesn't seem to realise how much her parents spoil her, while Steve understands his mother is rich, and seems to appreciate her, though he is very snobby and spoiled. They used to be friends as they were Henry's enemies, but in Series 5, their friendship ends as Steve makes fun of Henry's school during competitions, which Margaret attends. She may also have a romantic interest in Stuck-Up Steve.

Margaret meets Bossy Bill in Horrid Henry Tells the Truth and figures out that Bill and Henry are enemies as he was willing to help Margaret write those bad things about Henry. Margaret was also there when Perfect Peter had beaten up Bossy Bill in Perfect Peter Pumps Up and was hiding behind tables and chairs like everyone else, as they were scared of Peter's transformation. However, she didn't seem to know Bill in the early series, and as a result, didn't say anything about the situation.
