at this point, you've covered about 90% of the main questline without alienating anyone. This will give you additional legendary/unique equipment at Proctor Teagan's store, as well as allow you to get Danse as a companion again and finish levelling him up to get his companion perk. Do X8-66 and get his companion perk, because you may be about to lose him. also, I'm not sure if allowing the courser to take back the synth in "Synth Retention" is an issue with the Railroad, I sneak-sniped the synth dead instead of letting it get captured alive just to make sure. Do Institute quests until Mass Fusion, taking care not to kill anyone in Bunker Hill except for the courser, into whose pants you need to sneak a grenade (everyone will be friendly but busy trying to massacre each other). Make sure you don't kill any Synths, except for reverse-pickpocketing grenades into the pants of specific mission targets and running away without killing all the rest. Finish all the radiant quests, as you they will fail after the ending. Do Railroad quests until Underground Undercover. Do Minutemen quests until completion of Old Guns.
Don't do the last step to check in blind betrayal yet. Make sure you ask for the network scanner back. Get into the institute using minutemen.Ĭomplete BOS main/side quests up until the last step of Blind Betrayal. (I'm writing this as much to get it sorted in my own head as to answer your question :))
