Synchronicity

When Jim goes to Abby's apartment for the first time, you can read on the intercom :"Sebastian, J.F. #2019". J.F. Sebastian is a character from ब्लेड रनर (1982), set in 2019, and directed by Ridley Scott. Just above is "Scott, Anthony #2012". Anthony Scott, aka Tony Scott, director known for Top Gun (1986), Spy Game (2001) and Crimson Tide (1995), among others, died in 2012 and was Ridley's younger brother.

At the beginning when Matty is putting the MRD inside the 'holder' to insert it into the machine, Jim says "Hold exposure to no more than ten seconds" and starts counting down from ten. Jim's warning is not very clear, as it takes at least twenty seconds from the time the MRD is exposed to when it is put into the machine, exposing Matty and Chuck to its lethal radiation. Before Jim issued the warning, it had already taken Matty about five seconds to pick it up and put it into the 'MRD holder.' The time from when Matty actually picks it up and puts it into the machine is about fifteen seconds. It would have made more sense if Jim had started his warning with "Remaining hold exposure..."

Also, exposure to radiation has a gradual effect. It's not something that is perfectly safe at 10 seconds, and then deadly at 10.1 seconds.
