Questions & Answers about פתאום הוא ראה שהפתק שלה עוד בתיק שלו.
ראה is the past tense, 3rd person masculine singular form of the verb לראות (to see).
So:
- הוא ראה = he saw
- היא ראתה = she saw
In this sentence, it refers to he saw / he noticed.
Because Hebrew often allows subject pronouns to be omitted, but they can still be included for clarity, emphasis, or smooth narrative flow.
So both of these are possible:
- פתאום הוא ראה...
- פתאום ראה...
The version with הוא is completely natural and may help keep track of who is doing the action.
