Being watched is not an remidable quest.You cannot repeat it.Is that sad,but surely TS will make this remindable (street spirit/playcube/another thing).
Yamiya.... best thing to do when something like that happens is to click the bug icon in the game, located in the upper right above the chat pane, and submit a report. You could also submit a report here: http://www.glitch.com/help/report/
That will generally get you help faster than posting in the forum, although the staff members do read the forum quite regularly.
If it's still in your quest log, look at the log (press L from the game window to see the log) and click the "Try it again" button, if there is one there.
