Actually, you can. Just make a new post with the new vote. You could even tag the users who voted for your plan and ask them to switch too. Probably won't get everyone, but it's worth the effort.
Then I'll just use the one that Schielman updated.
So
@EVA-Saiyajin,
@ReaperofInterest,
@Crimson Doom,
@CosmosQueen,
@Akasha,
@DinoHank , could you please update your votes to replace the bolded part?
[X] Trust no one – Verify everything you've been told before making a decision. You don't trust either party in this situation, but you can't completely rule out that Tattletale is telling the truth. And it wouldn't hurt to have Perfect Storm do some digging of its own for verification, so you'll take a rain check for now.
-[X]But make it clear that
she's the one asking
you for help, so it's best for her to watch what she says and who's secrets she's throwing around. You're well within your rights
to take her down to the PRT right now since she's prying into your secret identity
and she's a Villain, so it's best for her to keep that in mind.
-[X] Begin by telling her that if we were really as crazy as she says we are, she would probably be dead right now. Possibly ask her if the cops and robbers thing is how the world works, or just how she
wants it to work. We are already moving carefully to minimize the probability and potential impact of our actions beginning a gang war, but leaving things as they are is an even worse option no matter what she tries to tell herself.
Only worry I have is that the optional third paragraph add-on might split the vote.
Actually, as long as you have the main vote, you're fine. It should be counted with the rest of the people who did the Trust no one vote.
