As If

In Sooz and Jamie's room, we see the photo art piece of Jamie sleeping in the park that Sooz completed in episode 406.

When Jamie's cooking the meal for Sooz, Katie and himself we hear the sound of a doorbell announcing Katie's arrival (or so Jamie thinks - when he answers the door it's actually Tyler). However the flat has an entryphone with a buzzer not a bell, as we have already seen in this and the previous episode.

The Indian restaurant and takeaway that Jamie, Sooz, and Alex's flat is situated above, is called the Tandoori and Balti Palace.

When Katie introduces herself to Jamie in College, she says that she is lost. But then she says 'You were here last year weren't you?'. How would she know he was there last year if she's new. And if she's not new, then why exactly is she lost?
