This video just seemed like a nice old guy and a sweet young girl greeting each other in an informal way.
It looked like Pope Francis was the one who took his hat off. In a separate picture, that girl's hands look like they are in the traditional mode of prayer and not the combined fists look. I may have seen that wrong.
The other comments about Pope Francis here are absolutely right on. I think the rest of his time in the "office" is going to be good fodder for the Catholic websites.
