Posey met Miles "Tails" Prower at a Sonic-Con, and was the resident Sonic expert there. They exchanged pleasantries and she showed the sidekick to the podium for his speech. While she was interested in his speech, Posey and the rest of the audience saw Dr. Ivo Robotnik crashing the party. She encouraged Tails to fight off the doctor. When Tails went down, she stood up to Robotnik and demaned him to leave. Before Robotnik could crush her, Tails got up and defeated him. With Robotnik leaving Posey thanked Tails by giving him a kiss. They headed back to the con, while Tails said to Posey he has more of his speech he wants to tell her.
