"I'm really not sure about this."
"Trust me, it'll be fine; this is a controlled experiment."
"I've seen what happens when you let the power control you."
"That's why I've been working on these headbands; they limit the flow of energy from the Crystals to a more manageable level."
"I just hope you know what you're doing…"
"I'll never put you at risk, not after all you've done for me."
"OK; tell me when."
Sally presses a few buttons, toggles a few switches, and enters a few commands on her computer; in moments, the system is ready. "Commence inhibitor band test sequence alpha."
"Commence the what now?"
"Fire gravel at that bullseye fifty feet away."
Danny unleashes a measured and focussed stream of gravel at the target; he hits the bullseye dead centre.
"Good shooting," Sally compliments. "Now do it again, but this time, don't hold back."
"Are you sure?"
"Absolutely; give it everything and then some."
Danny takes a deep breath. Surrendering control, he allows the full power of the Earth Crystal to flow through him; he fires at the target again.
The gravel beam is identical to the first.
"…and that was a perfect test!" Sally grins with satisfaction. "Am I good, or am I good?"
"It's definitely impressive," Danny compliments, repositioning the yellow headband. "I just hope we never have a need for them…"
"Me too," Sally agrees. "Now, just twenty-three tests left; onto sequence beta…"
