Several dates were marked out, although most markings weren't identified during the flash. Some of them, though, were seen:
- October 6 - the day of the GBO - was marked, although it wasn't seen with what.
- March 9 was linked with a string to a photo of two men, one of which is wearing an old-fashion diving suit.
- April 12 was linked to a photo of two elephants lying down.
- April 29 - the day featured in the flashforwards - was marked "D-day"
As the first step in trying to recreate the wall, Mark and Demetri attached the eight sheets to it, and marked October 6 and April 29.
