Ianto is the very definition of calm, and he steadily expands the sphere, making sure to visualize it as the same 'thickness' at all points. He has a hidden core of willpower that rarely needs to come out, but he taps into it now, pushing against the attack.

Gwen flounders for a moment when she doesn't get an answer, trying to figure out what's going on. But it doesn't take her long to put the pieces together, and her shields snap up. She doesn't know if this is the right thing to do, but she visualizes her sphere as the metallic silver panels of the sculpture, with water flowing over it to misdirect the attack, trying to deflect it away instead of pushing it outright.

Tosh takes a few deep breaths, then turns her attention to the task at hand. Her shields take on a strange blue, oscillating sort of tint as she subconsciously begins picturing her power as coming from Mainframe, the computer that controls the Hub.

Owen scowls as he figures out what April is doing. He has a strong fight response to fight-or-flight situations, and that sometimes comes with a disregard for his immediate safety. He throws his shields up but it's slapdash, easy to crack, and he'll be the first to fall from her probes.
