1 Lucas: If we turn the lights on, we’ll alert everyone that we’re here.
2 Dustin: Whereas using these flashlights is totally inconspicuous.
3 Lucas: You don’t understand. We have to use the flashlights.
4 Dustin: Why?
4 Lucas: They’re cool.

I refer to them as "flashlights" in the comic only because the theme is set in the USA and the kids are American. Normally in Australian (and British) English you'd refer to those things as "torches".

I understand that apparently this causes great amusement when we write that we're using a torch to look around in a dark place, and Americans think we're using a stick wrapped in rags, dipped in oil, and set on fire.

Although honestly that would be even cooler.
