Larian Studios Forums Divinity: Original Sin 2 Divinity - Original Sin 2 - General The Doctor without Lohse

Sir Lora opened the door for you? that's hilarious.
Wow, I didn't even know you could enter by the basement. This explains those suspicious barrels then.
I think the front door only opens for Lohse. The door speaks to Lohse and then everyone can enter.

I talked to the Doctor first, using Lohse. When they finished the conversation, the battle begun with 2 of my characters, the other 2 were hiding behind the door next to the Doctor, that leads to the basement.

If the Doctor already starts at the basement for you, then things happened very different for us.

Edit: I was just reading about this quest on Fextralife, https://divinityoriginalsin2.wiki.fextralife.com/Doctor's+Orders. You gain basically 2 MILLION exp points for killing the Doctor and all his 10 minions.
If you never finished this quest with Lohse, there's something very special that happens when you defeat the Doctor. She sings a pretty cool song, it was one of the most memorable moments of the game for me. Maybe the most striking moment. Search for the song on youtube if you didn't hear it yet.
