He entered since June and seems he only worked so far in the Tea Party Summer event, which was well-received but doesn't prove much in plot quality for now.
Though the fact he is (one of?) the Summer writers indicate he is now in charge of Trinity or Tea Party, which was of core importance for the Chapter 3's plot and tied with Arius' plotline which kickstarted the Chroma subplot.
I don't think we will see much of him since BA has been focusing more on Millenium and Decagrammaton lately. Most likely, he was put to write on the long run plot while they already were preparing the conflict with the Prophets.
