Why do so many capes have this attitude of 'I will figure out which of my abilities are lethal as I go, by trying them on people I do not intend to kill'? This is not a new observation but it is a very frustrating pattern. Armsmaster doesn't want to be so much better than everyone, even though he obviously is, he wants everyone else to be minimally competent!

An engineer doesn't build a bridge to figure out if it will fall down. The PRT should send all heroes through engineering school.

"It is very important to know the damage your weapons will do to a target before using them. You would be liable for any harm you cause, whether intended or not. The PRT can provide power- and weapon-testing facilities and help to affiliated hero capes, I suggest you raise it at the meeting tomorrow."

"I'll do that then. It makes sense, I'm just not used to being able to kill things or people I'm not supposed to. And it seems like different types of attacks might be interchangable than I'm used to."

"Are you a recent trigger?" Either that or she spent a long time building her weapons before getting into a fight, which would have been reasonable if she had then spent some of that time testing them on acceptable targets. Like pigs.

"What does that mean? I did tell the people at your building that I'm from a long way away and I just got here."

"...did you acquire your powers recently," he clarifies.

"No, I've been like this for about fifteen years now."

She said she's not used to being able to kill people she shouldn't. That implies she was either limited to strictly nonlethal attacks until recently, or else that she hadn't fought any people she wasn't 'supposed' to kill for the past fifteen years until she came to Brockton Bay.

That is a very troubling implication but she probably misspoke, other people are rarely precise with language and the odd construction 'kill things or people' indicates she may not be a native speaker of English. In any case, if she showed restraint against Lung she can presumably refrain from murdering anyone until morning when they can question her properly. And she is a veteran cape (hero?) who wants to cooperate with the PRT and who just helped take down a major villain, so he shouldn't risk antagonizing her.

"I see. I need to escort Lung; I will be at the meeting tomorrow morning if you have any more questions for me."

"Okay. I'll see you then."

Well if this is done she'll go check on that beach party again. Is that still going?
