Yeah, this is pretty dumb, but I just had these thoughts, especially with her being an assistant to Twilight, with Cozy Glow’s differences being she’s evil, she a pegasi and instead of wanting to be accepted as a little brother(witch Twilight and Shinning do, or always have) she in my theory may want to be seen as an adopted daughter of these two, who I believe she admires greatly, while Chrysalis and Lord Tirek grew up with stories about Emperor Grogar, Cozy Glow who may be an orphan, grew up with stories about Queen Chrysalis and Lord Tirek, and was inspired by them, she perhaps see’s them as role models.
