is this the only saved file you have, if not I suggest just starting from the last one you had before this scene.
just to clarify, Manny is stuck, continually walking into Glottis right? You can't turn him around or anything? have you tried every button that the main menu of the game mentions, even the "p" button? This isn't really technical help, but just advice for how you might knock Manny out of this cliqche (or however you spell it)
