Kieran would stay!
He decided while he was looking at the evil spirit.
Kieran wasn't sure when what would happen when he left the hospital. Would he face a single evil spirit or a person that could create evil spirits or even maybe an entire organization behind this plot?
If it was just a single evil spirit, it may be solvable despite the troubles but if it was the either of the latter…
Troubles would be doubled or tripled and it would lead to his demise with evening the slightest misstep.
As for his identity without a background, Kieran was prepared to go full on rascal on the C.O.
Kieran pretended to be an amnesia patient, even if the female C.O. suspected anything, she wouldn't really do anything to him.
All she would do was put him under surveillance.
This was one of the restrictions of Kieran's identity. It provided him with convenience but at the same time restricted many of his moves.
