John is in the park already, avoiding watching whatever might be on his disc. He has it on him, but he doesn't know when or if he'll watch it. He sits on one of the benches near the butterfly pavilion when he hears Leia walking this way... in more than one ways. He's not trying to pick up thoughts, but it happens whether he tries to or not.
But he wouldn't need to read her mind to see, she looks upset.
"Hey, Leia. Are you okay? Sorry I heard you coming before you showed up. I didn't... hear anything specific. My telepathy just doesn't shut off unless I make it."
