lol These captions--well done!
I would just let Seruria think that: you would have to be a fool to put her above best girl Eleanor. Seruria talks a good talk, and walks that talk too--but that's only until "succubus instincts" kick in, and she's at least looking elsewhere, like with that phallic turtle. Meanwhile, Eleanor only has her sights on you, no matter what.
There's simply no competition.
