There are a few good reasons why it took Indigo so long to make use of the bathhouse. One is that she's simply not too keen on public bathing, both because she wasn't raised that way and because she's a bit shy about her 'body'. She's petite, you see, not only in stature but in feminine curves. Not to the point of looking like a child, but yes, there's not a lot going on there.

But not even she can resist the idea of relaxing in the hot water forever, so after looking around the Market to make sure no one else is around at the moment, she makes her way inside. Eventually she sinks into the hot water of the bath, curled up with her arms around her knees in her shyness, just in case someone does come in.

Perhaps it's boredom, perhaps from the relaxation of the hot bath, but after some time in the bath her head begins to bob. As the area around her darkens, though, the glow of her body does not, as her environment simply reflects it less; so now she stands out from her environment even more. Eventually, after a while of fighting off drowsiness, it claims her and she dozes off. Her 'face' is the same as ever, though, and the only sign of her being asleep is the darkness around her and her lack of movement.
