This isn't so much a prediction than it is a general idea, so I don't really want it put up as a prediction, but anyways...

I have a feeling that "Immorality and Sinners" is titled as such because the two sections I think the next chapter will be in cover these two ideas:

Immorality: Erza and Mira get to the ex-Chairman's house and learn more about Face and the White Legacy. However, when they learn the names of those linked, they find out the linked people never got asked to be tied to Face, rather, they were linked without being told, so as to stop the information of Face and how to access it spreading. That would be the immoral part: linking people to Face without their knowledge. It would also explain why not even other members of the Council (Michello) don't know who are linked, and could tie into Jellal/Ultear not knowing much about Face if they turn out to be one of the 3.

Sinners: Jellal/Ultear is one of the linked, tying in how Jellal and Meredy will enter the arc, as either way Erza/Mira/both will have to go find them.

Welp, it's just a thought I had... I dunno :/
