Shakespears Sister reference
In the episode where Alex meets her future husband, clearly visible amongst the records in his bedroom is a copy of 'Stay' by Shakespears Sister. At the time of watching I thought it was just a terrible error. However after listening to the song recently I realised it was almost certainly intentional. The lyrics really fit well with the overall plot of the show. For example;
You'd better hope and pray that you'll wake one day
In your own world
'Cause when you sleep at night they don't hear your cries
In your own world
This must've been intentional, the song fits too well for it to be a coincidence.
God is in the detail
