Jimmy was rather surprised; he originally thought they were going to conduct some large operation, so why did it now seem like it had turned into a surveillance mission?
He looked at their positioning. Because of the lighting, only the position in the middle of the house was relatively bright, and his current location happened to still be within the shadows. After finding a passageway to the house's side, Jimmy quietly crept closer to the house and slipped through a back window. Observing the people inside the house from outside was very difficult because he didn't know if the people guarding around the house might suddenly turn their heads and spot him, so it was more reassuring to just go inside and observe.
