Sakura reveals to Sasori that she had taken an antidote to his poison, that she brought with her. Meanwhile, Deidara attempts to split Naruto and Kakashi by creating a swarm of explosive jumping crickets out of his clay and has them pursue Kakashi. Kakashi makes a shadow clone as a decoy and the crickets, mistaking the clone for the real Kakashi, detonate harmlessly. Kakashi then catches back up with Naruto and formulates a plan.
