Why was she so sure (Spoilers)
Mick was dead at the end? She went into the burnt remains of the house and saw the spear in the wall and Mick's body was nowhere to be seen. Yet she goes on as if he's dead and her mission is over and moves on with her life.
And no his body couldn't have been burnt to ashes or anything they'd be a burnt corpse there for sure, the fire wasn't that bad, there was parts of the house still intact.
Thats what i love about these high school girls, i get older they stay the same age.
