Biography
The unnamed girl awkwardly greets Barry Allen and tells him to make sure he says "I do". She informed him that she felt the wedding would be "one for the ages". Barry asks if they knew each other, to which she replies they didn't and she was no one special. She reappears and excitedly pays for Ralph and Cisco's drinks while babbling intellectually. Afterwards she is seen writing in a journal using the same symbols as Barry when he returned from the Speed Force.
