I thought it was a fairly decent chapter. Its only a matter of time before the perpetrator who's watching this makes another move and initiate the hollowization of the other 6 would be Vizards. after this chapter, the only loose string left will be the Hougyoku. that the only thing in this Gaiden that needs to resolved. I imagine the Vizards will be subdued eventually by Tessai and Urahara, but they'll be placed under arrest by the Central 46 and SS.
