Confidence is a Plant of Slow Growth.Despite his injuries, Kotetsu leaves the hospital to find Barnaby, who is faring badly against Jake. Kotetsu tells Barnaby he has figured out that Jake can read people's movements using super hearing as a second power, and gives him a sound grenade as a countermeasure. Although this grenade initially seems ineffective, it turns out to be a stun grenade, causing Jake to drop his guard and letting Barnaby defeat him. Kotetsu reveals that Jake's second power is actually in fact mind reading, proposing a fake plan to Barnaby in order to mislead Jake. Kriem threatens to blow up the city using the mechs, but they have been taken out of commission by Karina, Nathan and Pao-Lin in the meantime. Jake tries to escape, but when he shoots at Kotetsu, he hits Kriem's helicopter instead, causing it to crash on him. At the end of the episode, Barnaby addresses Kotetsu by name, a sign that he now trusts him as his partner.
