I'm looking for information on a devotee named 'Rahul' who was sent to listen to the readings in the Wada. What can you tell me about him from Chapter 18?

The provided passages from Chapter 18 do not contain any mention of a devotee named 'Rahul'. The text does describe Sai Baba's practice of sending devotees who came to meet Him at the Masjid over to Sathe's Wada to listen to the sacred readings. Chapter 18 highlights Bapusaheb Jog as the one reading the books and mentions that Baba would send many devotees to listen. It also references Madhavrao (Shama) in a separate incident involving a message from Baba about Dakshina. However, the name 'Rahul' is not present in these specific source chunks, so no information can be provided about him from this text.
