The third point of view:
If Reina had run to the hospital, then Niklaus had zoomed over like the flash. The instant he heard that his daughter, Isabella was rushed to the hospital, his brain stopped functioning and it was as if he went back to twelve years ago when she was just a problematic kid and he was the father who almost developed a heart attack from her troubles.
Yes, Niklaus loved all of his children equally, but his relationship with Isabella was on a different level. She's his first fruit and product of his youth, hence he would never joke with her.
Once he got to her private ward, Niklaus was prepared to kick the door open only to discover it was open halfway already. He took a step forward when he heard familiar voices from inside and halted. It was his wife Reina and his daughter, Isabella.
