Yeah, they are going to be filming nearby to where Aqua died in his previous life (Ruby also actually since she died under his care), that is why he thought of the hospital when they told him where they are going to be staying.

The dissatisfaction that is shared with the reader/viewer and Aqua at having an unfulfilled revenge plot is something I hadn’t considered before. Aqua is currently questioning what his purpose in life should be much like we are now questioning what is the driving force of the show.
