'How I Met Your Mother': The women in Ted's journey

"At the time, we were definitely unsure of how much Sarah Chalke we'd be able to get since she was awaiting word on the fate of 'Scrubs.' That made planning out the story arc trickier. We loved Sarah and surely would have planned even more episodes with her had her schedule been freer, although ['Scrubs' creator] Bill Lawrence was so supportive and helpful, and we were thrilled to get what we did. ... I’d say she's probably Ted’s most significant relationship aside from Robin. I mean, he was literally minutes away from walking down the aisle with her before it all turned to crap! Stella also goes down as the biggest emotional ass-kicking we've seen Ted get, as she decides to reunite with the father of her daughter instead of marrying Ted."
