I heard that you're supposed to open her invite for her after you've talked to Anthony? I did (I even did it after I talked to everyone, too), but she just said that same line about having a familiar face? I refreshed the page a lot but nothing changed.

Do I need the open invitation from Anthony in my inventory or something? Because I kind of read it to one of my pets. :|

You need to open the invite and go through the dialogue with Anthony. Unfortunately, reading it to your pet will not suffice. :( [edit]

Nevermind, I read that wrong.. Is Anthony the only other person you talked to? I talked to all 4 of the others before talking to Abigail.
The "plot guide" recomends reading Abigail after all the others..

That's strange, it should work because the only people you really need to talk to to advance the plot is Anthony and Abigail. Did you go through Anthony's whole dialogue by refreshing the page? Maybe you could try opening his invite again just to be sure...

Yeah, I talked to her last.

Hmm, I may not have gone through all the Anthony dialogue? I guess I'll just refresh the page a lot the next time I dance with him. Thanks!

Did you read the free book? Because you have to physically read the pages in order for part of the plot to be activated. And then you need to talk to Anthony (all the way through) before Abigail.
