If there IS anything to gain, Sven would stay and detail the attack for LK, if he wishes.
I think practically, having delivered the report to Decimus, the Captain of the guard might oversee a patrol checking stuff out. As far as the Hobgoblin confession,
The one surviving Hobgoblin does not survive much longer. He speaks but only in pragmatic defiance. He gives a personal name, speaks of his tribe as 'from over the hills'. He speaks also of some treaty and that the Hobgoblins are in good standing with a local rancher, inferring perhaps this raid was not an isolated incident but a premeditated action. He points to a charred body as 'the Gaffer'. Just following orders is no justification and his execution is swift. A tight noose and a kick away of the bucket he stands upon.
the local rancher infers the Bresnan Ranch commune which though backed by Ollis, doesn't yet incriminate him in any duplicitous actions.
Connections might be raised, Decimus is of St Ygg's and loyal to Vicar Othar who contends often with Ollis over policies and influences upon Krothos. So he might add an implication rather than yourself. At this point Krothos has no reason not to trust his Chamberlain.
Of the four figureheads in the Old Manse (Krothos, Vicar, Ollis & Decimus) you might find the latter the most trustworthy to take into your confidence.
