Lifetime Piling Up

Lying in a coma after his race car accident, Nathan dreams of what life would have been like if Dan had stayed with Karen and Lucas instead of marrying Deb and raising him. In this imaginary world, Lucas would have been raised with the Scott wealth and stature, and Nathan would have been the one growing up on the wrong side of the tracks.

Lucas imagines if his and Lucas's lives were switched. 

Haley learns that Nathan doesn't want her home.
