Delano nodded at Neo's orders, but was looking around, hoping to see the intruder, if it was Simba or someone else.
Simba, after informing the rest of his pride about what he had discovered, had gone with Nala and a few lionesses towards the Outlands. He wanted to get Astra back, but only if it was her choice. He also hoped to avoid a confrontation so he had the others stay back as he spotted Delano and Neo, and approached them, making sure that they spotted him. "I did not come here to fight," he announced, "only to talk."
Delano tensed when he saw Simba, and let out a low growl as a warning, but didn't attack as he normally would. He eyed both Simba, on alert, and Neo, for any signal on what to do.
