When Batman came over, it was obvious for a moment that he thought Dick was talking about Tim's presence, which is probably why he frowned particularly deeply when Dick practically ignored Tim and pushed the camera towards him. Dick tried to look innocent for as long as possible, but Batman clearly wasn't having it.

Bruce lifted a hand, beckoning Dick to follow him, before turning and stalking a little way away. Wincing, Dick followed him and there was an obvious whispered argument happening. Neither of them raised their voices enough for Tim to catch anything of what they're saying, but it was clear that Dick was in a lot of trouble. He waved the camera at Batman insistently, trying to get him to focus on the important thing, and finally the older man took it and watched the video. A few minutes later, Dick returned and crouched down in front of Tim.

"Hey...so... you really can't come out and do this anymore, okay? And Batman wants to know a bit more information so he can check up on you, because we're worried about you..." and he knows she probably doesn't want to get her parents in trouble, but there isn't really any avoiding it now "but the video is really good, okay, and it's really helpful, so we're pleased with that."
