To elaborate on Starlight's hiding spot, it is the upper maintenance girders above the Gas production zone, which is right by Playcare. Starlight doesn't leave the GPZ because since the Hour of Joy (HOJ) alot of the employees are on the catwalks. Starlight tends to go out of the GPZ to find injured toys and help them, returning them to their former glory. Starlight saw player kill Catnap, so knew he was a wild card. Starlight recognized the player from when he was still Leroy Cerwall, and felt a bit of bitterness towards the ex-employee. Starlight follows the player throughout chapter 4, even witnessing Doey finding the player, and Starlight froze. He hadn't seen Doey in 10 years, and seeing him made Starlight a bit hesitant since the war divided the two friends, Doey on Poppy's side, and Starlight doing his own thing. Doey and Starlight knew each other even before the experiments. Leroy knew Kevin and Mark, as he played with them.
