Pont looks like he wants to start arguing with Harlow -- and he does try, starting to stammer something about his other daughter, but a curious glance from Harlow shuts him up quickly. In a setting like this, he's one truthful blurt from having his prior actions exposed -- and that would likely spell the end for his little upper-echelon lifestyle he's been clawing towards. Honestly, I'm impressed by Derpy's level of restraint to not just blast him now that she's got him trapped.
