Though there are undercurrents on Ruth's side, the four who could potentially have a direct confrontation each have their own reasons for restraint, so for now, things remain calm.
First, Oliva... his actions are not excessive, the meaning of the test is strong, but he doesn't act harshly.
Although he is not very willing to see the presence of Koyl and Rojas, Oliva understands that relying on himself to restrain the unpredictable Aislin is unlikely.
Even though he temporarily pulled Aislin a bit using some of the well-preserved yet potentially centuries-old strange object aroma from Gilbert, it only gave Aislin a glimmer of hope, not that she could resist the true owner of the soul.
He and Ruth are pleased only that Aislin might have a chance, even if a fragment of her soul enters the Styx after everything ends, not that Aislin can play a major role in the current affair.
