I knew for a fact that one or more of the Endless were responsible for Isabella's Event.
The description hit me too close to home, and the chances of this being random, considering the lengths the First Daughter had gone through to force the Infinite Hotel's Event, were zero.
However, the only Endless I knew was the First Daughter, so I had no way of telling which one of them was involved.
My only option was to trust the Hotel Girl's judgment about who was behind everything.
Any doubts I had were immediately dispelled once I entered this building, though.
It just so happens that before I had received Isabella's event notification or even entered the Infinite Hotel for the first time, Claire had asked me to buy her a phone to play a game she had seen online.
This game was interesting in several ways, but the most important thing was that one of the main characters was Isabella herself.
