Thanks, Leni! Honestly, I couldn't imagine how to actively resolve that for Snape because it was Harry's POV---I couldn't come up with a satisfying conversation to that end, and really just hoped it was understood that Snape was experiencing a gradual shift in perspective of his own. Which, of course, might've happened much sooner if the man wasn't so stubborn. Not to mention, it was wrapped up with the fact that he genuinely didn't want Harry to leave (though he wasn't intentionally keeping him hostage, per se).
Anyway, I'm sorry that little bit felt unsatisfying to you, but I'm really glad you enjoyed the rest of the fic. Thanks again!
