You are, either as one of Pucci's agents or someone from the Speedwagon foundation, trying to find Jolyne or someone of her crew in the Green Dolphin prison. After successfully having blended in the place, you try to find one of them based off the info you were granted. It hasn't been too successful so far, until you find an... Interesting sight.
In one of the showers of the place, you see what appears to be a lone prisoner with green hair lapping away at the floors of one of the showers.
