I think that might be Mari's, it seems closer to a link or purple color in the dark than a blue as would be from Sunny's, and I think Sunny's bed would be in the place of the crib where he slept previously and not where Mari's was. Also her hair appears to be in the bed, probably from her facing away from the viewer
So Sunny here presumably kicks the bucket and Mari is left with nothing but memories and grief
