"This is a warehouse." The Bat wad very good at pointing out the obvious. The woman inside was as well. Leaving both the money and what was no doubt a drug where the boy had tossed it, the Bat approached to take the lighter. The gloved hand turned the shiny surface over and over before there was a soft hmph of a sound. It wasn't the thug's lighter, and Zoe would return it to the proper owner.
"It has many weak points." This was more the soldier than the Bat talking. "Your traps are only momentarily effective, and they anger more than deter. The ones that do damage create a mess in your own home. You want to deter with damage, you do not do it in your own home unless it is the last resort."
The Bat never addressed the "Indian" comment because Zoe had no idea what he might be talking about. Alfred had not been able to give her all the information she wanted, and the Bat's helm was helpful in capturing images of the boy and his surroundings. She'd have more answers to understand.
"They will return with more dangerous weapons, which may destroy much of the warehouse. They will be careful should they think there is anything of value, but the rest will be demolished." The Bat probably knew pirates much better than Rufio.
