Not a lot of time to get emotional? He had 9 hrs in the car. :-/
Not seeming emotional is not telling in and of itself IMO. Lots of people go to great extremes to not be emotional in front of others (me included). It's also possible that his saying he hasn't had a lot of time to get emotional was meant more like not having wrapped his head around it. Shock and having a perceived purpose such as handling things and getting to children can delay the emotional breakdown. Again, IMO
