Iapetus is likely showing up quite early (though clearly not as early as the hardworking Stefan or his aids). The Tytalus is quite happy to chat with Stefan in Spanish, and even help with the loading if the hands are needed and he isn't going to be in the way.
"Ah, Stefan," he says in his native tongue. "You work is looking excellent as always I see. What have you prepared for us today?" He pauses and shakes his head, interrupting himself. "No, no, I am getting in the way here. You are hard at work. Do not mind me."
Iapetus is carrying his usual travelling kit, a pack, some requisitioned rope, his armor and weapons. He almost looks like he's not a magus in his gear, or perhaps more like a militus Flambeaux. Though he clearly doesn't carry the typical Flambeaux dislike of the moors, as his delight to interact with Stefan shows.
