@mary_duan@Miss_DP Samuel is still in the same world with Dan. Dan wakes up in 1994 but I think he's still in the other world rather than having time travelled. He will through that world communicate with Melody and we will see her flashes of her perspective at the Visser seeing Dan in her dreams..
@mary_duan@Miss_DP I think the Samuel we see dragging Melody at the end is just a projection from the demon as the demon knew Dan would second guess following creepy Samuel anywhere, hence his hesitation. The demon wants to keep people in his world.
