Before Argon had made his move on Zephyr, confronting him about everything last night, there was a talk between Raven and him.
Raven had warned Argon about how he was bound to lose, but Argon hadn't believed it.
Still, Raven had gone on, telling him that even if he didn't want to believe in it, he should listen to what he should do in case he did lose.
He had told Argon that after retreating, he, along with all the other elders, should hide in the Cradle, and once he gave the signal, they should come out.
"What signal?" Argon had asked.
"Well, you'll know without me telling you."
That was all Raven had said, and true to his words, Argon and the elders knew when they had to come out.
That whistle from Raven was the signal.
Since then, everyone—including the elders, branch family heads, and Argon—saw everything that went on, including the persistence of the squirrel army, which made them wonder if they could ever be that good.
