I am trying to convince Diane to speak against the khans joining with the legion, my quest arrow guides me to Anders, but there is no dialogue related to the quest.
I've tried to get work from Diane, but she doesn't trust me due to my bad rep(shunned) with the khan.
I don't have the speech necessary to get Jack to side with me either.

:[

Anders is the guy on the cross in Cottonwood right? If so, just letting him down is all you need - he goes home and she's all good with helping you after.

How do I let him down exactly?

Bump

Is there any way to gain rep with the Khans? Already taught Jack 3 chem recipes.
I read about the quest and it sounds like I need the quest Diane gives to complete the one I'm on, but since Diane won't give me it due to bad rep I'm stuck.
