Continuity mistake: When the Ace Gang are sitting down talking about the snogging scale, Rosie has a lip gloss, passes it to Jas, Jas uses it, gives it back to Rosie, who gives it to Ellen, Ellen uses it, then gives it to Georgia. In the next shot, Rosie has it again without it being passed back along.
Continuity mistake: After the Ace Gang have been talking about the snogging scale and have spotted the Sex Gods, they're stalking the boys. Next time you see the gang, Jas has a different hairstyle than she did before - and everyone else looks exactly the same so it's unlikely it's a different day.
Dave the Laugh: You're beautiful.
