What's her next course of action?

Venture into town

Despite her humiliation, Rita couldn't just stand and going back in the water was a dead end.

So she started walking, despite being in the general area of Halemark, she was still far away from the actual city itself.

After 3 hours of a slow walk with both arms keeping her covered, she decided to use the advantage of being in a empty areas. Dropping both arms, she was able to break out into a Sprint.

She arrived at the outskirts of the city just as the sun began to dip below the horizon.

Hiding behind a rock, Rita considered her options; she could continue down the beach to where there were probably people or she could break off into the woods just up the hill where she could probably be undetected longer.
