She got off in Ternes

On the first wagon of the 2 train going to Porte Dauphine I saw a girl. We locked eyes a few times from Pigalle until Ternes where she got off at 9:40am. She was wearing big headphones and standing by the door. The thing is, I’m pretty sure I have seen her once before at the airport in Madrid in February 2016 on a flight to Lima.
