Yes, I'm sorry, I should have been more descriptive. It would be a follow-up reading. If a reading indicates something will happen then you would use the the card that suggests it as the significator.
The book indicates the Ace of Wands represents Spring. "Tarot Made Easy, by Nancy Garen", uses the Ace of Wands to represent Autumn and Ace of Pentacles to represent Spring. I'm using the Sharman-Caselli deck and the image of the Ace of Wands appears "Autumn-ish" to me so I use it to represent Autumn. I'm fairly new to tarot, is it just a matter of preference or is there a set rule as to which suit represents which season?
Sorry for the confusion, I'll edit if necessary....
