The only solution I can think of is changing the result so it kills Heyden as planned, but that would require me to change the way I decided to set up voting for this game (which I guess wouldn't be a big deal for the sake of future Days). A tie was the last thing I wanted, but Bianca's last-minute change of heart complicated things (combined with the vote mechanic I chose).
If you guys are up for that, I could do that. But that's a last resort, given the circumstances.
