I have nooooo idea if this is the right area to put this topic, but here goes anyways
Also somebody might have already asked this somewhere but I’m too lazy to look for that. Or maybe it happened in the books and I’m just ignorant.
I was thinking about how in WoR how Tyn is able to draw an Angerspren when she isn’t actually angry (I assume as Shallan commented on how it was impressive she was good enough to draw one), and I was thinking about faking emotions on Roshar. So I figured, what if a Lightweaver made fake emotion spren to help fake an emotion? Could Aon lightweaving (perhaps on a seon) do this? Would investiture detection be able to tell them apart? Uh there are probably other things I should have thought about but didn’t, but oh well. Whooooo wants to prove me a complete silly here?
