Bad Day was standing outside the building where Russell and Saran were, looking down at their room from the rooftop.
Although the curtain blocked the view of Saran's location, Russell was exposed in the outside half.
Even though Bad Day's prosthetic eye had infrared vision, which could reveal the view beyond the walls,
it was precisely because Russell had intentionally stayed on the outside half that Bad Day could rush over to find their exact location immediately after receiving a message from the Deer Leader.
Before going to Saran with Cui Que, Russell had made it clear to Bad Day two days earlier—to be on standby during this period.
Bad Day did not have a chip, so he couldn't receive messages; however, Russell could call for his help through the Deer Leader.
To avoid alerting their quarry, once Russell and others entered Saran's office, they could no longer send messages.
