I agree - it does feel like they're going in that direction with this season - i wonder if they have decided to wrap after this season......???
although I don't want Robin and Barney getting married - that seems too easy at this point.
as to "who's the daddy" - we dont' know how much time passed since Robin slept with Barney, and it wouldn't make sense that she'd tell Barney instead of Lily, if Barney wasn't potentially be the dad.
I don't like the spoiler for next week - it takes this show to a place it shouldn't go- I'd much rather a false positive.
