Delay Was A Good Thing
Keep in mind that the only reason why Brooks was able to watch Haley giving birth is due to the fact the flight was delayed. If it wasn’t, he would be on the plane when labor started and he wouldn’t see a thing. In this way he was able to Facetime the whole situation.
We can even add that he is one of just a couple passengers who were happy due to the delayed flight. This problem had a good outcome after all. All we can wait now is for Brooks to come to the hospital and see his daughter for the first time.
