I'm trying to get into Filian's head.
She knew she needed a new model, so she commissioned one and planned a debut, right?
She at least went to the trouble of setting up an ARG and doing all that kayfabe about disappearing and wanting to show us her world.
Obviously she wanted some time off between the Minecraft marathon and the debut, to give her a chance to mentally recover, spend time with family and friends, to set up the new studio, and to make people forget the old model a bit.
Surely this was the plan, right?
A couple of weeks for Christmas and family time, a couple of weeks in Japan and visiting Layna, while the ARG drip fed people with clues.
The people who made the ARG must have been told by Filian how long the solve should take, and they would have put the right number of timegates in so that people felt like they were making steady progress.
So what changed?
Did the ARG people mess up?
Did she not pay them enough, or not give them enough advanced notice, so they didn't prepare enough steps?
Couldn't they have added new steps after the ARG started if people were making progress too quickly or if Filian decided she wanted to spend another couple of weeks seeing friends?
Something must have gone wrong, or at least she must have underestimated something.
Did she not realize how much she would enjoy not having to stream?
Has the pressure of being a streamer, or having to debut, finally caught up with her and she's got performance anxiety?
Did she get injured while on vacation or doing stunt work and now is waiting to heal?
>TLDR It just seems like she never would have intended for the gap to be this long, and something must have happened which is outside of her control and that she doesn't know how to communicate to the people who are waiting for her return.
