You think so? He seems like he's very protective of his family. Especially when he is willing to sell his golden ticket cause his family needs the money, I can definitely see an ISFJ doing this. He's quite, humble, imaginative... those traits can describe either ISFJ or INFP, he kind of has this humble but steady vibe I get from ISFJ's.I think INFP is more likely. He comes across as more of an idealist NF than a guardian SJ.
