Because, honestly, Don was the least developed multi-episode character ever on this show. Heck, even Britney Spears's character was more fully realized
I just... I'm trying, you know, to connect how Robin deals with break-ups (Simon, Barney, Ted) to how she's been dealing with this, but... I can't believe she had any feelings at all for this loser. Especially not so much that she left a series of increasingly violent messages on his voicemail. Yeah, it's a sitcom, and realism is sometimes sacrificed for a joke, but COME ON.
I know you wanted to go all Joss by giving us what we "need" instead of what we "want", but you know what I need? Good storytelling. I don't care in the long run if the pairings I like are together or not, but I do care that I believe what's happening on the screen.
I did like the Ted story, though, so thank you for that.
Shucks, I looked it up. It's Abby. Mandy is kinda close?
