When I go in Jorrvaskr my active quest tells me to go down to the Jorrvaskr living quarters and the quest arrow leads me to where Kodlak is usually sitting but there is no one in the seat.
Kodlak is dead and everyone is "mourning" but when I speak to anyone in the companions they act as if nothing happened.

For example I have the option to train from them still and ask "why did you join the companions?".

Will it still work for me if I start the quest to retrieve the helm of winterhold and run through driftshade refuge or use invisibility potions to get the helm without killing anyone? (I have a saved game right when I started Bloods Honor and before I have killed any witches).

Note: I have not cleared driftshade refuge and I have not completed the quest to find the helm of winterhold.
