All very interesting

My theory is: In-universe, it was a failed attempt at a resurrection, or else an effort to at least convince himself he would return as he's clearly undergoing VillainousBreakdown at this point. Out-of-universe, probably a way of teasing us as to whether Bill could potentially make a return (though it was said this was the final episode), or else making fun of how fans always speculate of villains returning even after they're dead (and sometimes they do)
