I just discovered the Covenant location, when arrived Swanson told me I could enter with any problems. Then their mayor(or chief in charge I don't know) told me to not talk to Honest Dan.
Here's the problem: I can't find Dan. I just checked the wiki and after a quick read I discovered Swanson was supposed to ask me some questions in order to let me in, that never happened. I also discovered they hate synth and the Institute. I went to the Coventant after ending the main quest siding the BoS so I assume they know I was against the Institute but how do i trigger their quest?
