Good plot twists, well integrated. Best so far on this site imo.
(don't trust that spellchecker! I noticed several correctly spelt but still incorrect words)
ps: one final twist: I reckon Pelli's murder could have been intended to be the mechanism to activate Roku to kill. Otherwise that was a mystery. Pelli could have been supplied the betti paige erotica to foster her attachment to Roku. Also Pelli's almost-death practically did activate Roku.
