Talk to Warf next to you. Ask him about the reading, tell him to get a tissue, then tell him to look busy. He’ll walk up the bridge and when he stops, talk to him again. He’ll walk further up and stops at the top.
When you talk to him again, he’ll disappear behind the mountain.
Walk up the bridge, and follow Warf. When you’re standing at the top, walk to the left to see where Warf went.
