He’s emotional, but holding it together. He’s observant. He can’t hold too many things in mind at once, can’t imagine delegating or asking others to do things for him. He doesn’t have a private life of the mind but he does share feelings with his family that are different from those shared in public. He’s considered quite smart among his peers, because he can think ahead so well. He’s sad now. Thinking ahead doesn’t do him any good. The immediate future isn’t a problem he can solve now. So he tries not to think ahead. But then doesn’t have his tools to problem-solve. He's trapped with his feelings. And this brings him near to tears.
He’s distracted from how he feels, by excitement at what he sees.
