- Sometime after Nathan Ingram's death Finch hires a man named Rick Dillinger to help him prevent crimes involving the irrelevent numbers from the Machine. (“RAM”)
- Daniel Casey's number is pulled out by the machine on December 4.[note 1] He is wanted by Control, the CIA, and Decima Technologies in connection to some code stored on a laptop when he worked on the Machine for the Government. Finch and Mr. Dillinger attempt to help Casey, while CIA agents Reese and Stanton are assigned to kill him. Ultimately, Reese fakes Casey's death and gives him a new identity. Dillinger, angered at Finch for not telling him the true nature of their work, sells the laptop to the Chinese. Dillinger is killed by government agent Sameen Shaw during the transaction.

Greer, the head of Decima, also tracks the laptop to Ordos. (“RAM”)
- Reese, Stanton, Snow and Corwin are stationed in Tétouan, Morocco on December 5. Reese receives a voicemail from a distraught Jessica. He calls back, and promises to be with her in 24 hours. (“Matsya Nyaya”)

- With the software secured, Reese hesitates before killing Stanton, who shoots him instead. She was given the same orders as him. Reese escapes the compound while the CIA bombs it, presumably killing Stanton. (“Matsya Nyaya”) [note 2]
- Peter Arndt goes bankrupt and owes Sullivan $3,000,000. His abuse of Jessica results in her death. He stages a car crash to hide the true nature of her injuries. The autopsy report is dated December 7. (“Many Happy Returns”)
- Although this date is not shown explicitly, it must be December 4 because:
- Dillinger mentions that it's Saturday at the beginning of “RAM”.
- The Machine starts fast forwarding back to 2014 from December 2010 at the end of “RAM”.
- Reese is sent to Morocco the next day,(“RAM”) when he talks with Jessica on the phone. (“Matsya Nyaya”)
- Jessisa's autopsy report is dated December 7 (“Many Happy Returns”) and the only Saturday in December before that day is December 4.
- The Morocco and Ordos missions were previously believed to have occured in May 2010, but after the airing of “RAM”, they had to occur after Nathan Ingram's death. An explanation to the inconsistancy could be that when it is mentioned by Snow in 2012 in “Matsya Nyaya” that an operative was attended to outside of Ordos in May 2010, he may have disregarded the timeframe only focusing on the fact that it was someone leaving Ordos.
