I saw this when I was in 4th standard and still remember the chills I had watching Dorothy get out of the well. Since I watched it covering one eye I thought of re-watching it today (ofc I got nothing better to do). In the climax they're supposedly selling the bunglow back to Fr Dominic for half the price. So they are supposed to get the box of money from Dominic. So why do they exchange boxes in this clip? something i missed?
