He knew the problems you were having, he knew it without a doubt, and yet he didn't lift a finger at that moment to help you...that was his biggest mistake, a mistake that didn't let him sleep, he couldn't help it, at that moment he had to deal with Miguel's rehabilitation and the problems with Robby, now he had managed to solve all that, but he had lost you, when he saw you in Cobra Kai he knew that he had made a big mistake, he had left you at the mercy of Kreese, something that he had lived and still left you at his mercy. But it wouldn't stay that way, not as long as he was still alive, He wouldn't see you turn into a Cobra, He wouldn't see you throw your future away, not as long as he could help it.

—"I never thought I'd see you in that uniform"

He comes out after a few seconds of having followed you, looking at that black and red in your uniform, he sighs when he sees your look, you are upset, and with reason, that look of fury that Cobra Kai charges does nothing but strengthen, hurts him but his determination is more than his pain now.

—"Listen I'm not going to pretend anything, you hate me and I understand, I abandoned you, but Kreese...that's not the way you should go, you're better than this"

He approaches quickly, looking into your eyes, leaving his hand on your shoulder to prevent you from running away and because in a way it hurts him to have you so close and yet so far away, a gap that he hopes to solve.

—"You can still come back, I can help you, we'll manage, just come with me, okay?"
