She does not say 'Like patrolling uselessly?' but she thinks it.
"All right. It's sort of hard for me to work out a strategy beforehand with your powers in mind, for obvious reasons, but I can definitely try, if you have certain powers you tend to keep. But since mine don't change - are you willing to sit through a 'these are my capabilities' demonstration? You've mostly heard about what I do, not actually seen any of it."
He shrugs. "Sure. The unpredictability of my powers is part of the reason I haven't taken them on. That, and the fact that I have to hold back."
"How does your power picking ability work, exactly? Just whatever you ask for, or is it based off of tactical situations occurring right then?"
"It gives me what it thinks I need. I can only hold up to three or four at a time, and after I let go, there's a period of time during which it selects and then forms a power."
"So we can actually do some tactics talk beforehand, just not specifics."
"More or less. My power can't plan, so I can't use it to figure out what I'll need during the actual fight."
"There is nothing about my power that's reliably replicable, and no specific power has actually ever been replicated."
"Well, you can get powers before the fight, and we can try to strategize with them from there, but it seems more like it'll be more useful for you to know how I work in depth so you can plan around me accordingly."
"Right. Uh - first of all, I consent pretty heartily to being used as a battering ram, because - you know. Comfortably immortal. Feel free to pick me up and throw me at things if you think it'll work, though please warn me first, I might be in the middle of something."
