I think this is the topic for this, sorry if I'm wrong.
I just made it to Ametrine City (The mountaintop one if I have the name wrong), and have just dealt with the house with the diary. Shelly ran off to confront Blake, and I am now supposed to meet the two of them in his apartment. When I enter, there's nobody there.
By looking at video walkthroughs, it seems that he's supposed to be at his gaming console and Shelly should be back one square and a few to the right, but there's just flat-out nobody in the apartment.
I'm unsure what all I need to give you guys in terms of information and whatnot, this is the first time the game's ever given me issues.
Thank you for any help possible.
