Because you're trying to pin Orphan's death on someone. Me, Brahne and Fujin voted for an Orphan lynch yesterday and then he mysteriously dies the next night. You can't target Brahne. She's too active, no one would follow that. So you have me and Fujin, both with he same relative activity. So you claim to have taken some type of action involving both of us.
Why would you switch Orphan if you knew it would make you look suspicious?
