What would be the "official" way to complete the following sentence?
She said she would collect the book on Monday when she _____ home from school
1. Came
2. Would come
EDIT: A few of you guessed correctly. I'm currently in France and this is a test my English teacher gave me. It was just 20 sentences to complete, similar to these ones. She gave an answer that I'm 98% sure is the wrong one, but I need to know why one of them is right/wrong before complaining about my grade.

Contrast your example with the same sentence using the simple future instead of the conditional:
Here the verb in the WH-clause is simplified to the simple present.
