He was minorly upset with his son Ben, when he acted coldly towards the team and even giving little emotion towards Ben seeing Diane as only his stepmom.
after the team is brought back to life and being told they couldn't find her, he hopes that she isn't in pain.
Before he is ready to pull the Diane awakes from her coma and gives an emotionless hug, and doesn't notice Diane more emotion (and nearly sexual moan) as she hugs Ben.
