So I finished the companion's quest "Blood's Honor", the quest where you kill the 5 hag ravens and collect their heads. I return to Whiterun with the heads, and the towns folk are outside the companion house, staring at the dead Silver Hand. I go inside, and the NPC there tells me Kodlak is dead, and says we're going to the Silver Hand camp to avenge him. I get quest completed "Blood's Honor". But no follow up quest.
The NPC sits down and eats bread. The other characters in the room give "Person is Busy" and I cannot do anything. I loaded back a previous game and reworked my way there, and same issue.
Am I missing something?
Edit: I went in and killed every killable Companion. This let me talk to the 'leaders' and get the repeatable missions from them, but I couldn't advance further.
