Wake Me Up Later
26. Fishing
Even if Nico was accustomed to the life of a demigod, that didn't mean he didn't wanted to deprive himself from 'fatherly' activities – like fishing.
That would explain why he was by some lake in the US (he thinks he's in the Great Lakes, but he's not completely sure) fishing. He went fishing three times in his life, two times with Bianca and one time at camp.
The sun is rising and Nico can see the Sears Tower and he realizes he's fishing in Chicago. He feels himself smiling.
