This is a minor point, but if you want to say that Willow gave your character a homemade flashlight, you're welcome to!

I would just make an IC post about this, but I'm feeling a bit burnt out on RP lately so I'm taking the easy way out. Canonly she does all sorts of computer/robotics repair, so I think a flashlight is well within her abilities, and she would be happy to give one to any random Joe she comes across. So just reply here with if you'd like her to give you one, and I'll remember to assume they met sometime and she handed one over.

(Note: she is not a factory and is limited by what supplies she can find, so she won't be able to make a whole ton of these.)
