I think he is. And as I interpret the other posts, I am not alone with that opinion.
Anyway, good ep.

@Swallow Your Soul:
Think about it: a year has 52 weeks and 4 seasons (normally called spring, summer, autumn and winter).
52 / 4 = 13.
So a series with 13 eps and 1ep/week isn't half a season (for that would be 6.5 eps) but a whole season and a 26 ep series a double-season.
