Everyone keeps bringing up her nearly getting knocked over. If you don't use the traffic lights and pay attention at that crossing it is easy to have near misses. Honestly, hundreds of people a day ignore the lights and take a chance at that crossing, myself included, and i've had a few near misses just crossing there when not in a hurry. It's an extremely busy part of the city, the cathedral, restaurants, bars, shops, bus stops, people heading to the train station. The clubbing district is just up that road and round the corner. If you are in a bit of a rush those lights are a pain in the backside to wait at.
All of her behavior is totally normal until she gets to the river. Until then she is a normal person going about her business exactly like the hundreds of people almost getting hit at that junction, or popping into the cathedral on their way somewhere. Hell, she might have gone in there, walked around, had a cigarette, stopped at the bin and left.
