It's winter and everyone at camp half-blood is out and having fun in the snow except for Will. He is in his cabin and doesn't want to get out of the bed because it's too cold for him and he'll freeze. Nico is at the Apollo cabin and is trying everything to keep Will warm. He put the heating to max, wrapped him in three blankets, and gave him tea. Will was feeling better but it was still not good enough. So Nico sat beside Will on his bed and hugged him so that they both could be a little warmer. They stayed like that the whole night watching movies and enjoying each other's company.
