The actors looked sorrowful while carrying white roses and lit candles for the scene.
No word yet on who the vigil is for. Of all the things the Glee cast spilled, this was not one of them! We could make an informed guess, but for now we'll just say that it looks like this scene definitely takes place in New York. Do with that information as you wish.
