After working around the "Fire Support" bug (Where Danse says "Check your fire" after the ghouls are cleared out) by continuing the main quests until "The Molecular Level." Danes will bring you to the ArcJet Systems plant for the "Call To Arms" quest. Once at the door he will turn around and go back to the police station, and will not respond the The Lone Survivor.
After Paladin Danse begins to leave the plant, the objective "Follow Paladin Danse" appears.
The mission can be continued by fighting the Synths in the plant until you get to the Deep Range Transmitter and the objective "Provide fire support for Paladin Danse" appears. Once the synths are wiped out and the fire support objective is complete (even without Danse there) there will now be two open objectives. One saying "Speak To Paladin Danse" and the other saying "Follow Paladin Danse"
When trying to speak with Danse back at the police station, he does not respond.
