I agree the evidence isn't 100% conclusive, but it does suggests that there may be more going on here. The body double does look a lot like HRC and is shorter than HRC. With a mask on, about the only tell is the height. HRC also doesn't seem like the type that would be big on high heels -- too feminine for her, methinks.

After all is said and done, though, there are arguably better places to start with normies than this.
