In Friday night's Dollhouse episode, is Summer Glau really saying "You routed through an io9 to seize control of my chair?" It appears so. Check out the clip and Tim Minear's actual script for the episode.
After a few of the commenters on our Dollhouse recap pointed it out, we decided that maybe we weren't just having Friday-night aural hallucinations and Glau really was saying "io9." So we watched again, and sure enough, she is. And the Hulu closed captions appear to confirm it, although they render it as I-09. Behold:
Update: The episode's script is actually online — with some interesting bits that didn't make it into the final episode. And in the script, Topher says, "Route the chair's I-09 directly into the ground feed," and then later Bennett says her line, as reproduced above in the closed captioning.
(For those of you wondering what an io9 is, here's how we defined the term when we launched the site.)
