Oh! There you all are!
If Jake went to Anna Scher Theatre School (as reported at the beginning of the thread) then he wouldn't have automatically had dance training, they don't offer it.
Anna Scher, despite having a number of very successful alumni is essentially an after school drama club run from a North London church hall. They get a hell of a lot of graduates into Eastenders, and it's very affordable. It's not a 'stage school' in the way popular culture refers to stage school, whereas Italia Conti (where Natalie studied) *is*.
By the final, I didn't mind who won out of Natalie/Abby. Now with hindsight, I wish it were Natalie. Loved that showdance!
