Here's why it's significant:
* Paul's personality: Paul is a quirky and somewhat awkward character. He doesn't always say the right thing and sometimes uses words in unusual ways. Saying "wizard" instead of "good" or "great" is characteristic of his playful and slightly offbeat personality.
* Contrasting with Juno: Juno, on the other hand, is sharp-witted and sarcastic. Her use of language is much more direct. Paul's "wizard" interjections stand out against her straightforward style, emphasizing the contrast in their personalities.
* Their relationship: Despite their different personalities, Juno and Paul develop a close bond. The "wizard" word becomes a bit of a shared joke between them. It's a playful way for Paul to express his affection for Juno, and she seems to find his quirky language endearing.
The word "wizard" isn't meant to have a specific meaning beyond simply expressing Paul's enthusiasm or approval. It's more about his character and how he interacts with Juno.
