I'm obviously not an expert but her vocal technique doesn't sound particulary healthy. Like, her voice sounds strained most of the time, and her tone has a grating quality that not everyone is gonna enjoy.
And she stopping twice on her performance was awkward asf, like, girl, you are on national television, c'mon, that was not exactly professional from your part.
Season 20 was actually an interesting season for this. The wildcards were Allegra/Jay/Mike/Tristen. Only Allegra was eliminated immediately after at Top 14 - Tristen made Top 11, Mike made Top 10, and Jay made Top 7.
I really don't see Roman, or even Jayna, getting more votes than her... When's the last time a saved contestant suddenly survived the next cut? It was usually back when they saved one at a time that they had a better shot.
