At what point does he officially join Chaldea in the plot? While I know the whole idea is that in plot nearly all of the Servants are in Chaldea, but after seeing some of the vids of Part 2, it's clear that Sherlock seems to have somehow gotten a far more important role than expected. How come he became a main cast member? Did it happen when he was introduced, or has he become a main cast charecter only since Part 2?
