they pulled some really tricky shit with this one. first, they set up ambiguity for his death with all the "kill confirmed" bs. but they draw his armor in super fine detail on the halo 4 recap page. flash forward to the diadact on the last page - different armor. i'm betting its a different guy.

plus, that can't be 343gs. it's the monitor from gamma halo (istallation 03). if we follow the naming math of the other two monitors, we see that monitor# = 7^(installation# -1). 343=7^(4-1). 2401=7^(5-1). So i'll bet that this monitor is 049 adjective noun. well, as long as 343i can keep their canon straight. Maybe Reticent cournucopia or something.
