Virginia was constantly honing her skills as an infiltration expert. If she was traveling from one room on a ship to another she didn't use the halls and corridors she used the duct work. She watched the Freelancers mingle about like rats waiting for their cheese. One of them, Colorado she thought was standing still almost under the vent, she ran through several scenarios in her head about the numerous ways she could kill him. She grabbed hold of the vent cover and extremely slowly moved it so that the motion trackers wouldn't pick her up. She then pulled out a Type-2 Antipersonnel Fragmentation grenade aka Spike Grenade used in training simulations from the small of her back. She 'armed' it and tossed it exactly between his shoulder blades, a spot that Colorado couldn't reach to remove it by himself.
