Welcome to the thread!
I haven't contacted Emma. On Twitter, one fan asked her if she voted for Lorna and another wished her good luck in it, but none there have actually explained what the vote is.
Over on instagram, one person tagged her on a post about the vote. I think Emma looks at instagram more. But overall Emma is much more active on Asian social media that I don't use, so maybe she's posted or heard about it on those services.
As long as we're talking about Emma Dumont, gonna give an off topic plug for her that the new Wrong Turn film that she's in just released in theaters a few days ago. I'd go see it if not for COVID. I'll eventually see it video on demand though (if it's on services that will let me). I also saw What Lies Ahead (free on Amazon Prime) starring her and Rumer Willis, and that movie was... okay. Emma plays a much more innocent and vulnerable character in that film, and her performance does great at selling that impression for greater tension. So on her front individually I'd say she did excellent.
