Josh Radnor, Britney Spears and Sarah Chalke  by Monty Brinton/CBS Josh Radnor, Britney Spears and Sarah Chalke by Monty Brinton/CBS

In last week's Q&A, Josh Radnor discussed with us the new batch of How I Met Your Mother episodes. And then the Britney Media Hurricane hit. A man of his word, Radnor got back to us - via e-mail - with his even more recent thoughts on Ted's assorted prospects arriving in this Monday's episode. - With reporting by Michelle Heller What's it like working with Sarah Chalke?
It felt like Sarah and I had worked together for years - in the good way. She's super talented and funny and brought such a great vibe to the set. We did a two-and-a-half minute tracking shot the first day of shooting, which was one of the funnest - is that a word? - things I've done on the show. She's also really believable as a doctor. She must have played one at some point. Since Sarah will be in only one episode, will Ted and Stella still be dating?
Doesn't look that way, but like with everything on the show, they've left it open. Maybe all of Ted's women will come back for the series finale.... It'll be like The Bachelor meets the last episode of Seinfeld. Considering Abby's (Spears) crush on Ted, does Ted's interest in her boss create any conflict between Abby and Stella or between Ted and Stella?
Hmm, does this question have anything to do with who's playing Abby? No conflict, on or off camera. Abby's crush seems to amuse Stella and annoy Ted. Is Abby's interest in Ted returned at all?
Only accidentally. A few times.
