Hmm, well, she could be doing a variety of things, really. At quieter times, Sayla enjoys some good reading or meditation in a confined space. She could also go for a stroll within some nice scenery. Maybe even spelunking.
At louder times, when she's feeling more adventurous, she might just be her merry Jedi self and go seek out those in need if not on an actual mission. This is really combined with her interest in waltzing about cities and such, enjoying the architecture and the people, even if she doesn't seek to talk to anyone.
