She isn't Arya Stark. She isn't Maisie Williams. Here, she is 'Lorraine' - just your average shop clerk who's "never acted before" and wants to hand out free Game of Thrones merchandise to avid fans - but, as we all know in life - nothing is ever really "free". Usually there's quite a hefty cost to your dignity.
Prepare to see GOT fans earnestly reinact scenes from the show, all while trying to convince Maisie Williams that she is Arya, with statements such - "you're 100% Game of Thrones". While some are willing to play along, there are others who actually don't know they're being pranked.
Fair play to the folks at Nylon for keeping Williams even busier during her already hectic promotional duties for the show.
