The idea of tapping into someone’s memories has been discussed more than once over the years (like this). Remember that the medical erasure process has already been recommended for Sean since he was very badly beaten and raped. Medical erasure could wipe this from his memory and after the scars have healed there would be no trace of the trauma mentally or physically. Of course, this procedure has not taken place yet, so Keiji is able to, through the superconductivity of the regen pod, tap into some of Sean’s latent, near term memories. As we see, however, they are fairly sketchy.
If we stop to think about our own memory, it rarely plays back as a continuous movie. It’s more like quick edits of what we saw or said and almost never includes audio, yet audio can often play a major role in triggering us to remember places, people and things. It is interesting to contemplate that accessing our memories from the outside, might just include audio and more.
We shouldn’t be surprised that Keiji isn’t getting a clearer picture though he could if he could get direct physical contact with Sean. By so doing, he could, theoretically, scan right through the event in its entirety. The complication here is that there was evidence that Sean was headjacked, (another topic I have blogged about numerous times), depending on the quality of the device and the trauma involved those memories may or may not be in tact. In fact, Sean’s memory could already be a disconnected pile of snippets not unlike the event we have just witnessed. He may not even know his name.
Season 4 begins next week April 10th and it kicks off with 4 double-page spreads in the Prologues section. Interesting stuff about the world of 2159, maybe some clues, maybe some foreshadowing.
