I don't own any of the characters in and I apologize for grammar/spelling mistakes.
Will had let Nico leave the infirmary in three days but forced him to stay in his cabin for a week until he could get back on his feet. Nico put up an argument until Will had threatened to pick him up and carry him, bridal style, to his cabin in front of everyone. Red-faced Nico had shut himself in his cabin and refused to come out. Somewhat satisfied, Will brought him meals which he ate little of until Will shoved a fork-full of food into Nico's mouth. The boy fed himself from then on while the son of Apollo watched. Slowly, the son of Hades began to improve.
Roughly two years after the infirmary ordeal
One morning, Will went to go wake up Nico and see how he was doing. He knocked on the cabin door. "Hey Death Boy! Open up!" Will yelled knowing that for sure would get the cute son of Hades awake. After a surprising five minutes, he knocked again. He put his ear against the door and heard muffled sobbing. Will quickly threw open the door and there sat Nico shaking from the sobs that left his mouth. Will quickly shut the door and wrapped the boy in his arms. Nico tried to push away at first, but fell into the embrace a few minutes later. They sat in the dark cabin while Nico's sobs filled the silence and broke Will's heart. After a good ten minutes, Nico pulled away and told him about his nightmare which had involved Cupid, Tartarus, and Bianca, his three worst memories. Will listened quietly to him. When Nico finished, Will leaned over and kissed him on the forehead. He was cool to the touch. Nico pulled away quickly and locked eyes with the son of Apollo. After looking at each other for a few minutes, Nico yanked Will in, making them both fall onto Nico's bed with Will on top of Nico, and their lips touched. Later, when Will went to get Nico something to eat, Percy asked him why his hair was a mess and his clothes were rumpled.
