Until Irahl finally figures out how to escape the restrictions of his human form, this is probably the closest to being outside of a cage that he can possibly get. Even when walking around freely in the open city, he's hobbled and hidden.

Right now, he is enjoying being truly off-leash.

Down here, the water is much colder, especially in the murky shade of the lakeweed forest. As if his long braid doesn't create any drag, Irahl disappears into the plants with surprising quickness. Robin is still able to see the rough shape of him enough to and give chase and catch up, but the details of what exactly he's chasing are hard to make out.

So, when Irahl apparently finds some sunken object large enough to push off of, Robin will be surprised when he suddenly has Irahl turned around and lunging for him between the weeds.
