Small theory on the plot...

Just throwing this as a theory out there...

Given the two titles the film has been associated with so far have been Day 6 and Mother, I can assume that Jennifer Lawrence's "tranquil existence" is disturbed by a group of ppl, the leader of which is her mother, played by Michelle Pfeiffer, who proceeds to wreak some sort of havoc (emotional probably, or otherwise) on Lawrence and (probably) Bardem, and has the most influence over the events (not too many other reasons I can think of for potentially calling the film Mother), which come to a head on the 6th day of their stay with both mother and daughter going at it...

Thoughts??
