The Guardian (S03E04)

After an examination at a hospital, Arturo (John Rhys-Davies) tells Quinn (Jerry O'Connell) that he has been diagnosed with a terminal illness. Quinn convinces him to continue sliding with the group, and they land in a San Francisco of the mid-1980's. They have not gone back in time; this Earth rotates faster, causing a slowing of time. Quinn sees a funeral in progress, and realizes it is his father's. He recognizes a boy as a younger version of himself. After the ceremony, Heather Hanley (Leslie Horan) stops to talk to Quinn. She is the boy's home room teacher, whom Quinn had a crush on. (iTunes)
