Empire makes an educated guess, from what they have seen during various set visits in February and April, that "Silva's MO has something to do with computers and the control of information".
Computers and the control of information - Yes, someone (Silva or people working for him) hacks the flash drive on Tanner’s laptop – this happens just before the explosion at MI6.
Then there is that computer wall screen (Scene 97) this is roughly where in the film I’m expecting the Hashima Island sequence to be... and Bond first meets Silva there.
Could this ruined and seemingly deserted place be his base of operations?
