Anya had no plans to spy on the three men in the open area. When running away from Alvin, she saw the third man side-eyeing her every movement. She guessed he was waiting for them to leave. Hence a quick plan appeared in her mind. She had no time to voice her plan to Alvin or show it in action as it might get those men's attention. So she just held Alvin.
Alvin was just following her without believing his ears. His naive, innocent Little Donut turned out to be a pervert to have an X-rated imagination of him with those men. He was thinking about how to teach her a lesson when she caught him off guard.
Seeing his lips part, she covered his mouth and unawarely pressed him against the wall while her attention was on the three men to hear them.
Alvin: "..."
