Hmmm, Corbin doubts that's how these things usually work. If asked, he would also doubt that Harry's life was "ruined" by the potion.

He's silent for a long moment, thinking about things, about Harry, since with him here the ever present throb that is missing Caleb has ebbed enough that he can think about something other than worrying about Caleb or whatever it was that he was currently distracting himself with so that he didn't have to worry about Caleb. Turning things over in his mind, looking at them from a few different angles. Coming to some conclusions that he should have come to awhile ago if he'd given himself the space to think about them.

"Hey Harry?" He pauses, afraid to say anything more for a very long second and fuck something up.
