How I Met Your Mother comes back in a couple weeks - September 22nd, I think - and the spoilers/rumors are starting to come out. Ever since Sarah Chalke took the role as Stella, people have been trying to figure out if she's The Mother. I've read theories all summer. TV Guide has a blog post regarding casting that weighs heavily on Ted and Stella taking the plunge this season.
None of this means she's The Mother, though. Keep that in mind.
And anyway, I'm more interested in what's going to happen with Barney and Robin.
