Harry was, despite the danger of it, very pleased to be seeing Neville. He wasn't sure what it was that Neville wanted to talk to him about, but he was definitely willing to hear him out. He'd managed to find another safe place for them to talk - thankfully, they weren't hard to come by - and he was already waiting there, invisibly, when Neville appeared. He had been keeping an eye on the clearing around them, and now waited a moment, circling around to make sure Neville hadn't been followed.
When he felt that they were safe, he stepped out of sight before removing his cloak and stuffing it under his jacket. Then he stepped out, also tightly gripping his wand, and moved toward his friend, giving him a little grin. "What'd you catch us doing in first year, and what happened after that?" he asked, just to make sure it was Neville. That was something only he, Ron, Hermione, and Dumbledore had known about, so far as Harry was aware.
