The two men thought the death had probably broken glass mim. Because then everyone is Dim, but the stars. Episode mirror, mirror difference is probably going to have to scrap to mim until death.
Two people found dead at the hem fixed broken glass. Because that's when people tend to dwell on all the stars. I would go with broken glass shards of glass into the hem stabbed to death.
Both think that hem would die when broken glass. Because at that time everybody care but the stars. When broken glass would have a glass stab hem, died.
