It makes no sense that he would have the hankercheif on his hand and still be in Mary's company. Mary dies when he gets that injury. Other than that it's a great image, though.

Is this some game art?

I don't know anything about the ib world, but I can see in this pic that Mary (the blonde) is connected to the last (far right) painting, Eve is connected to the next to last (2nd from right) painting, & Gary is connected to the painting that looks like a broken mirror (3rd from right).
They are running to the darker side of this pic were the first three paintings also depict darker images.
I wonder if this somehow reflects the story that Dread above commented as making no sense in regards to Gary & Mary?

This looks a lot like some sort of evaluation of what's happened to all of them. Mary has the rose, Ib has his jacket and Garry has the handkerchief.
