I think that they are trying to make the Liza comparison i think i might just be too young to get it. I think that the way Granny said Eliza or Liza was sarcastic and that they were making fun of each other regardless of whether i get the reference or not that was the tone and the body language. And after hearing people talk about it the Liza Minnelli reference that makes enough sense to me that that is probably what they are talking about.
I totally agree with you (I dont even know who Liza is, but knew it wasnt a flattering name to be called 😆 ) – Granny was not happy when she called Ruby Liza, nor did she sound overly mad, more frustrated & in EVERY other Ep happy, ticked or otherwise (like in Red Handed for instance), she has been Ruby to everyone in SB.
Each to their own charming but as Ruby is listed ONLY as Red Riding Hood & Ruby in credits Im not willing to bet on her having another SB name- even in EVERY interview Ive read & seen she is listed under Ruby/RRH, no mention is made of any other name/s for her, so until I hear other wise from the EP/writer lips, she’s staying just Ruby on here 😉
