"Calm yourself, Ronnie! We've managed to escape that complication unscathed!" Harry paused for a moment, fully registering what he had just said. "Er, I mean...calm down!" That damn old man was rubbing off on him! He coughed loudly to clear his throat and started speaking again. "By the looks of things, I guess this green stuff is supposed to help plants turn into...whatever that was. But I never thought I'd find Green Thumb Ring here of all places." Harry was visibly starting to calm down, he had been embarrassingly panicky for a bit. Harry pocketed the green jug of liquid, he was still curious to find out what it was. It'd be best to leave before he gave Ronnie a heart attack. 

But there was one thing that he wanted to try. While he generally didn't use his skills in front of others, it was possible that he wouldn't get another chance like this. He slowly walked to another terrarium containing a plant. He used his telepathy to try and communicate with the plant. Judging by how the other plant reacted, these things seemed to have minds of their own!
