You pursue, two of you by one route, and one of you by a different route, and soon it is only too apparent that Rinley is indeed making for Arcadia by way of the rooftops!  However, between Horizon and the somewhat Gothy architecture there and the more, uhm, Japanese layout of the shop district, you have to scramble a bit.<br/><br/>Fortunately, it's early enough that there isn't a lot of traffic to get in the way.  That's good, right?<br/><br/>But...it does take you a bit to find out where the little red-haired scamp has gone, and when you do finally catch up with her, it's by running into one another at the foot of the ladder that will allow you access to the rooftop in question!
