The girl and the note must be from an underground group.
We can arrive at this answer because:
- The girl hands Winston the note very discreetly and she shows signs of anxiety.
- This shows that she is afraid that someone will see that she is secretly communicating with someone.
- The Thought Police would have much more direct ways to act, as they could accuse anything.
- That way, a Thought Police agent would not have to act so discreetly and would have to act out of fear of being found out.
