Sounds good about you not actually carrying the widget. Then you can play a decent part in the story after you arrive back and get patched up and still maintain your dignity as a professional hide-and-seek player.
I was thinking more along the lines of modifying the posts to make them fit rather than deleting them outright. Just to be nice. However, I can't think of what to do concerning the knocking the door down thing without leaving some inconsistencies in the posts of more respectable posters. The appearance of the building to them can be corrected, as can the time of day (now dawning, I believe).
You can do some regaining consciousness or whatever if you like now, and we can either assume you were carried back to the New World and everything played out as expected, or people can do a little back-posting to flesh out the details.
I don't know how the teams thing is working out. Gerald thinks he is working for the big official people down south, but is following the orders of Ninja, who isn't being entirely honest about his motives. Chris and his bunch are running their little hovel that is somewhat aligned to the official people that Clarke and Gerald aren't working for. You might be working for the big organised people too, or you might be part of Ninja's bunch. Of course, Gerald doesn't know the difference, so either you or Clarke are going to make the call on that one. Regardless, though, that still leaves the magic widget out in the ashes somewhere that nobody can find it in any short space of time.
