I like Draco very much. I was very sad when he died in Chapter 4. I cried.But I don't think you need to worry too much, because I think this is just the future of Vincent ，The bonus scene also said that the stalker and the tracker Backwater .We went back to the time line of the residence (because it was said that Vanora had the ability to predict)So Victor Line, we may have a different future in that line.
So we have to put all our expectations in Chapter 5，6.
