I remember that. Jack did everything to identify where she was, apart from dangling her Room key out of a window and shouting 'come on up! Mumma Jack is in town!' (Although there is no proof that she didn't). Even to the extent of pretending to take a picture of a car 'to show sb' that absolutely identified her location.I think that whole Edinburgh episode was some kind of message to Louisa - it was somewhere they’d visited together (I thought Louisa may have some Scottish heritage), then there was all that posing in her bra. She also seemed to be breadcrumbing some kind of local flirtation/hook-up potential (possibly related to someone at Dishoom). She’s so pathetic.
duck only knows what she was actually trying to prove.
