Thanks for the info. Her mom was Hitler’s sister, Angela. I wasn’t aware that Geli is short for Angela, but it makes sense now.
Julian’s Rum suggested that “You have a rival” may actually be code for “You have a(r)rival”, with the ‘r’ having been left out. He suggested the 18 min. delta between Q’s post and Flynn’s represents the letter ‘r’. Don’t exactly know why Q would code an already cryptic post, but I guess it’s a possibility.
