At a certain point while they were talking Joanna had decided '**** it' and slipped away. She had no idea what those things were capable of but if a Irraka couldn't get any closer without being noticed then they might as well give up and go home.

As she gets closer she will move very carefully and concentrate on staying out of everything's way. For all she knew these things were capable of noticing if someone was swimming nearby in a way that they were unfamilar with. Initially she is hyper focused at the behaviour of the things that were closer to her. If anything seemed to be interested in investigating the area where she's swimming she's prepared to slip away and start over. When she's absolutely sure she'll get closer to the structures themselves.

Joanna is tempted to get her phone out and try to take some pictures while she was down here but in the end decides against it. Whether or not her gift would hide the action she is firmly of the opinion that no one else should have to look at this.

If it still seemed that no one was paying attention to her she'll try to find the largest or most important looking structure even if it was accompanied by the biggest concentration of creatures. Ideally she'd like to find an entrypoint that was large enough that she could get inside without running into something without there being any room for her to get out of the way.
