GLaDOS tilts the platform's chassis slightly, in either a nod or a bow, depending on how you look at it. She's still working out how much (if any) lying she should be doing in this case, but the general lack of reaction so far is encouraging. "Not precisely. Or at all, really. That would be giving her far too much credit." No, wait - she should probably lay off the insults for a bit. "I am GLaDOS, the current head of Aperture Laboratories."
