Faced with the same young girl, Aldrin let his clones analyze the scrolls again, looking for the trace of her story. However, just like the first time with the 'clock' riddle, they found nothing.
So, instead of dealing with her again, he picked the blurry wall with the old sage.
The riddle was also like the previous ones, simple but phrased in a way that it was like it originated from the old times. And Aldrin easily figured out its direct and literal answer; history.
Just like the first one, he was presented with the three choices of telling the young girl the direct answer or approaching the old sage and figuring out why it was relevant to him.
