If Haru hadn 't known and fought in the war with one of the two ANBU disguising themselves as Chuunin he might not have recognized them for what they were. They did an admirable job of pretending they hadn 't been one of the swarms of shadows following him through Konoha since he had arrived there so he could give them that.

After Haru had brought Tora to the Hokage early, grinning unrepentantly to his Jiji 's shock, he had sent his clone out. The clone's mission was to stealthily distract the two vengeful shinobi approaching Hokage tower so they wouldn 't walk in while he was getting his report. Then, he had finally been introduced to the rest of his four-man cell and been given his mission.
