Before you start the sixth chapter of the inFamous Paper Trail make sure that you have performed all the activities in the fifth chapter. What is meant here is the optional, fifteenth, mission and examining the clues connected with it, on the http://infamouspapertrail.com/ site. Find the new yellow marker on the map and head towards it.
The starting point of the sixth chapter connected with inFamous Paper Trail, is in the side alley, in the North-Western part of Waterfront. Approach the yellow marker and, after you have connected to the inFamous Paper Trail Project page, confirm that you want to continue.
You will now have to chase Celia, i.e. "the paper bunny" again. This chase is no different from the previous ones, throughout the inFamous Paper Trail. It is impossible to lose the chase, because Celia will be stopping, on a regular basis, in wait for you to catch up. During the chase, use the Neon, or the Video powers, thanks to which you will not have any problems reaching the rooftops. This particular chase is a bit longer that the previous ones and it ends in the South Eastern part of Waterfront. Collect the Origami Dove that Celia left behind and reach the spot from which you need to send it, which is located to the North-West of here.
