"What you have in your hands is the XM99 Underwater Tranquiliser Pistol. It looks like any other handgun, but it has been engineered to fire 6mm tranquiliser rounds specially built to be just as effective underwater as in the air. I designed both the gun and the ammo myself. It carries several advantages to a harpoon gun - more compact, non-lethal and it doesn't give me nightmares when I see it. The 6mm cartridges I find my greatest contribution - normal underwater ammo is so slow. Who better knows aquadynamics than me?"

Delphine goes for a swim and gives Taeko's new gun a test drive. Near a pool, she can jump out of her wheelchair fine, but getting back in is problematic - that's why Todd Gudrun (the researcher that named her) is there.

Delphine Langley, Taeko and Todd Gudrun were created by me
