After the battle with the mech Jin armor had shattered in battle, leaving him open to the mech's attacks. Jin failed to defeat the enemy, but what struck him was having his Cloth taken from him. Pegasus was more than just a Cloth; it was an extension of his own Cosmos. But the moment it vanished from him, he felt like a piece of his soul was missing from him in that very moment.
The moment one of his allies cheered for the enemy to take his Cloth, and escape, he felt his world crumble before him. The same person that he spent most of his time trying to help she wanted to see him suffer a significant loss that would harm heir side in the war.
Jin couldn't understand her mindset, but he got his partner back, and the bound between them seemed secure than before. He felt that the connection between them would serve them well in the battle against Zero though he needed to learn the abilities of Pegasus.

After attempting to learn from the others, he found himself spending more time chasing after them than learning how to draw the power of the Cloth. Though something that was said to him during his pursuit would stick in the back of his mind while training with his Cloth, Kiran told him to wing it. But Jin took that as him saying do training on his own since nobody really showed them how to upon the different abilities of the Cloth or so he thought. Since that seems to be how the other Saints gathered their strength, Jin would follow suit while preparing for the next defense against Zero's army.

Jin heads off to do a little training, but before that, he confronts the woman that wished to see him lose his Cloth, even his life for being a Saint. However, Jin remained strong while trying to correct her; he also strengthens his connection with Pegasus in the process. HE made it clear that the bond between them was unbreakable no matter if the Cloth was in his grasp or not.
