Main Theories and Observations
The last 4 digits of Jessica's phone number "1102" were the code to the hotel safe in Entry 33.
The number 1102 backwards is 2011. There may be something significant about this year.
At about 2:06 some slight sound distortion can be heard when Alex comes up close to Jay. ~Seraph825
