The World Figure Skating Championships are in Boston, with the world’s best taking the ice for a step on the road to next year’s Olympics.

The event, which begins Wednesday, comes two months after a deadly midair collision in Washington, D.C, that claimed the lives of six members of the host club.

The chairs where Jinna Han and Spencer Lane used to sit are still there, and covered with gifts: cards and cookies, plants and pictures — anything that might have sparked a connection for their friends and fellow skaters.
