So when Spencer offered to pay for the drinks when she was with Marco, she used a credit card. I have a feeling that she used Rollins credit card to pay for it.
We know Spencer had his credit card on her because she was waiting for Aria to text her the okay so Spence could buy the train ticket to Phillidelphia using his credit card so it’d look like he left town in a hurry.
The way the directors made sure we saw a close up of her tossing the credit card on the check booklet thing kind of made me question if it was his credit card (picture of the close up at the top).
It would be understandable if she accidently used it, she was drunk and not thinking straight. We didn’t see her put it back into her purse either, it just cut right to the make out scene with Marco.
If she forgot the credit card, someone could’ve easily taken it and used it to buy a ticket to Baltimore.
I feel like I’m kind of stretching this but you never know with this show tbh.
