Look at Kendall's face. He's so scared to be in Hollywood and he's not comfortable with that. Kendall's not used to being scared, so he's already regretting the move RIGHT AFTER they get off of the plane. But then there's James behind him, excited and hopeful for everything that's about to happen and that makes it all worth it for Kendall.
Then there's Carlos and Logan. Logan looks excited. That's a little out of character for Logan-- his characterization would show you that he would be worrying just as Kendall is-- but then you take Carlos into account. He's right there with Logan and Logan's always a different person with Carlos. He's more willing to take risks when Carlos is there backing him up and go out of his comfort zone. Not only that, Carlos isn't wearing his helmet which is almost definitely his security blanket.
