Feel like DW A is slowly but surely losing his marbles and I feel like his headaches is making him go downhill (Something tells me that he is sort of becoming more...like B?). Something about his expression, his twitching of the lips, his burst of anger..He is changing...Fear that he will lose it. Especially with the constant torture of losing everyone he loves twice.
I feel like maybe in someway, whatever DW B went through, like being accused of murder. Would apply to A sooner or later, since he stated that everything has a connection, maybe when DW A loses it, he will go all out
