whether you ee Kelly at the busses or not is really a matter of a few different things...
There are times she doesn't go back to the bus, they stick her in a car and take her wherever (especially if she has to fly somewhere for something, or is staying over.. the busses don't park at the same hotel Kelly stays at so people can't find her). Sometimes you'll even catch the band in rental cars driving in and out.
They also tend to block the view of where Kelly comes out and goes to the bus.. if they can, depends on the venue.. they often sneak her past to avoid a huge mob scene.
but there are times when you just happen to see her.
