Little Miss Can't-Be-Single runs up to them. Hi, Ted. "Hey guys, Stella and I have a problem." Flash back to Stella and Ted in their cabinesque room at the Collective. She's looking over the programs from Nora's aborted wedding, when Ted tells her the good news -- Robin is flying in from Japan to attend. Stella misses the part where it's good news. "I'm not sure how I feel about that." Ted says, "Can I help? You feel...glad!" She gives him a dirty look and he reminds her that she likes Robin. Stella does like Robin, but says it's just too weird to have his ex-girlfriend there. Ted says it's not weird, but she insists. I think it's weird nobody's parents are there, or even mentioned. We flash to Stella's fantasy. She and Ted are receiving their guests. Robin hugs her and says, "Your new husband used to nail me, like, three times a day." Flash back to the present. "Having exes around -- I don't know -- brings up unresolved things. How do you know that that spark won't come back with your ex sitting out there?" Ted counters that they're just friends, and that he and Robin already had their backslide, last Thanksgiving, "Not even that long ago." Huh. Stella says, "Did you place a large bet against yourself in this argument?" Ted always bets against himself, Stella. He explains that Robin already has her plane ticket. Stella doesn't care. "Ted, it's important to me. I mean I would never invite Lucy's dad." Yeah, but Lucy's dad wouldn't have had to fly in from Japan, because despite the fact that you told us last season that he wasn't in the picture, he's local enough for Ted to tell you, "I wouldn't care if you did. Tony's great. Let's invite him, too." Stella gets really bent out of shape at that suggestion. "No! Tony is the last person I want at our wedding, okay? And... Robin is a close second." The rest of us get bent out of shape that an ex who was completely out of the picture, is well-known enough by Ted that he can declare him "great."
