Two questions I've asked Brandon but unfortunately I didn't record:
1)
Questioner: What would happen if an Elantrian burned or flared aluminium? Would they become Reod or a normal person? Or something else?
Brandon: Like if they got allomantic powers?
Questioner: Yeah, like a Lerasium bid or something.
Brandon: ok yeah, ahmmm I'm gonna say RAFO, I knew this one was coming.
2)
Questioner: Since the gemstones on shardblades seems to be infused with Stormlight, could a surgebinder draw that Stormlight and use it?
Brandon: No he couldn't. You see, that Stormlight is the shardbearer's life energy, you wouldn't be able to draw it just like I can't draw your life energy from you. If you were to extract that gemstone from the shardblade it is possible.
Questioner: But then the gemstone would go dark.
Brandon: Exactly.
