Jaber learned not to question Sindbad. Yes, he might be irresponsible, annoying, and carefree, but his instinct was the real thing. Sindbad had survived adventures no one else would have, and still, he willingly ventured back into the heart of danger with a smile plastered to his face.
Jaber never understood Sindbad completely, but he knew him enough to follow him to the end of the earth. So when his leader casually walked up the famous Golden Gate Palace, triggering whispers from the guards, he thought nothing of it, for Sindbad was a respected trader in Baghdad and a well-known adventurer whose stories traveled far and wide.
