I suspect another scare tactic coming up. Round and round the circle of three we go.
"Or until such time as he releases you from your servitude." "But then I'd have to bring your mom in for justice.." "Then you'd all kill me.."
I don't think that's what would happen. Seth already worked out that Salomere was being wrongly accused due to her reaction to Scruff's death. He took an oath to uphold justice, so even if law wa ta Salmore dead, Seth knows it's for a false reason and wouldn't try to kill her or Dorcan again.
