I thought the episode was really good, definitely one of the best. I liked Mo's backstory, especially with the secret about his grandad. I was kind of annoyed that his parents had cerebral palsy, though; I mean, what with Frank and Layla, it's way overused, and there's loads of other disabilities which the show hasn't explored at all. I liked the subplot too, though, Carmen hasn't had a storyline for ages, so it was good to see her at least having something to do. I found it kind of annoying how the events of the previous episode weren't mentioned at all, though at least there was the awkward scene when Carmen was interviewing Tee, and also when Ryan was being mean about Mo.
Miraculously, someone has actually remembered that the kids go to school! I was kind of confused, though, I mean if Mo is ten, that makes him the same age as Harry and the twins, so wouldn't they have been in the play too? Anyway, never mind. I should stop ranting about continuity. It was definitely one of the best episodes so far, and it was great that Mo finally had a storyline.
The trailer for the next episode looks pretty good too, maybe Tyler will finally have some character development; he hasn't really changed since series 1, and still acts like he's about ten, so him getting a girlfriend in the next episode will hopefully mean he grows up a bit.
