During Chapter 5 of Vampyr, you will start a mission called "And by The Sword you die". Finally, you reach the top of Pembroke Hospital, where you'll meet Geoffrey McCullum. A fight with a rather difficult boss fight awaits you. After that, you can decide what to do with Geoffrey. This time, you only have two options:
- Spare - This is a good choice. Thanks to it Geoffrey will survive. You will meet him later in the game when you have collected the antidote ingredients.
- Turn him - this is an extremely bad choice in which Jonathan Reid turns Geoffrey into a vampire. Interestingly, you will meet him later in the game. This time, McCullum will give up his life as a vampire hunter and give you the blood of King Arthur. Depending on the ending, the man can also chase you and want revenge.
