Another fun chapter, though it'd be easier to list all the manga series that DON'T have a secretly-evil church at this point. Dolores is probably aware that everything's bugged and everyone's a spy, so she's lying her giant ass off about manipulating Maria (though I did feel like she got along with her way too well from the start, considering her hate-boner for all things undead, so maybe this is a more realistic approach). Chances are that we'll get an arc where Dolores learns that everything she believed was a lie, leading to Maria supporting her when she's got nothing left, because dogs are nice that way, and then they can share True Love's Trib.
On an unrelated note, Sharon with her hair slicked back is hotter than everyone else in this manga combined, and I hope she gets a girlfriend, polycule or a raise.
