Yeah,Djura will be friendly if you approach him from the back entrance and talk to him, but aggro's if you attack him or any beast in the area. On the brightside, you unlocked his gear in the Hunter's Dream.

Eileen the Crow has an interesting quest-line that's easy to miss. If you screw up the order, you fight her instead of her normal end, which involves one of the nastier Hunter fights in the game.

The Beggar is Bloodborne's version of Yurt the Silent. He'll kill every NPC you save until you uncover his true identity and kill him... or just send him to Isofeka's Clinic and never worry about him again.

Barring a bunch of optional stuff you probably missed, you're not terribly far from the end. Bloodborne is pretty short compared to Dark Souls. Did you ever find the real Hunter's Workshop?

Shame you won't get a chance to play the DLC but totally understandable. Barring the pain in the ass fight with Laurence, it has some of m,y favorite boss battles in the game. The Hunter's Nightmare is also just cool conceptually and has some great lore with it.
