she was jealous of Renslayer and wanted to be a partner with He Who Remains. And she knows she can't be a full "partner" without a human body.

This episode ended with sort of a cliffhanger with Miss Minutes telling Renslayer that she knew a secret that would make her angry. We know from Episode 2 and the recording Mobius heard that HWR at some point did see Renslayer as a partner (the quote was something like "it's an honor to lead with you.) We can also assume that at some point that partnership ended, with him wiping her memory and placing her into the TVA. So maybe her secret has to do with how HWR broke up with her, demoted her, and wiped her memory.
