Okay, so I wanted to add a little side track story on to the end of Last Forever, as Ted's telling Penny and Luke the story of how he met their mother, at the same time Barney is telling Ellie about Number 31, and all his awesome stories from before, so that's the time frame, and let's just go from there, y'know! Enjoy :3
"And that, Ellie, is how I met your mother. Number 31."
"Dad I really don't think I needed to know half of that, nor did I want to." Ellie, the beautiful blonde haired, blue eyes, slim teenage girl said, looking on at her father, Barney Stinson. Ellie sat on the sofa next to Barney, in the appartment he had always lived in, as the Star Wars trilogy played out on the screen. "But this. These films, they're 'legen - wait for it - dary!"
"LEGENDARY!" The two said in unison. Barney sighed, laughing slightly. "It's not really the same without Ted and Marshall though..."
"Aw, hey, you've got me!" Ellie elbowed him gently.
"Yes! And at least you listen to my stories!" Barney grinned. "Penny and Luke just ignore Mosby."
"Of course I do, your stories are awesome! Aside from all the well, extra details which I don't really need to know..." Ellie referred to all the plays and perfect weeks, months, etc. that Barney had told her about.
"Oh come on, you're the product of one of them!"
"DAD! That doesn't help!" Ellie laughed out, grimacing slightly at the thought of her just being produced from a number. "Seriously, though, aside from that, your stories are amazing. Besides, Uncle Ted just talks about what a loser he was when it came to love, difference is, you were awesome and you found true love when you didn't expect it!" Ellie beamed over at him.
"Yeah... I did..." Barney said, pausing to think.
"What?" Ellie asked, noting his concerned expression.
"I was just thinking..." Barney sighed.
"About Robin?" Ellie asked.
"Ha, what? No, of course not! No! No, no, don't be so silly." Barney laughed, shrugging off the question, in a panicked tone.
"Dad, you haven't changed, at all. You're as transparent as a window." Ellie giggled at his reaction. "If you haven't forgotten, I'm related to you, we're the same blood, and you've raised me alone for all my life, I know you too well, I know when you're lying." Barney sighed as she spoke.
"Okay, yes, Robin." Barney looked away from his daughter, in a sort of embarrassed way. "But, tell me, I told you about Nora, Quin, Robin and number 31. How did you know it was her?"
"It's pretty obvious, isn't it?" Ellie looked over at him, Barney swung his head round and watched with a confused expression and Ellie sighed as if she had given up on him. "Remember what I said a minute ago?" She began. Barney nodded. "Same blood, all that jazz? Well, it's pretty obvious. I can read you like a book dad, whenever you're around her you're just, different... You're unsettled and tense like you're focussed on impressing yet you're relaxed and as if you've never been happier around anyone." Barney sat and stared at the tv as she spoke, he knew she was right.
"Okay, fine, I admit it, but no telling anyone okay? You need to promise me?"
"Why?"
"Because no one can find out, Robin and I tried twice, and failed both times. The amount of times Ted and I have argued about it, fallen out over her and ruined the group... No, we've got back on the rails, we've got time, we've got everyone again, I can't, Ellie, I can't."
"Why?" She asked again. "Look, dad, at least Ted found the one, right? He found her, and she wasn't Robin. The only one you've found had a three stuck in front of it. And don't even try to tell me you don't want to find her, despite your notorious past, I know you dad."
"Well then what am I supposed to do?"
"Think about it, think about how much you love Robin, how she makes you feel, if that feeling's not gone, not all this time, surely it's worth another go? I mean, who knows, 3rd time lucky, right?" Ellie watched her father as he leaned forward, deep in thought, he stared straight ahead as if he was mulling the thoughts over in his head. The suddenly he stood up.
"You'll be alright watching the rest without me, right?" Barney said, picking up a blazer to wear over the rest of his suit.
"Yeah! Go get her dad!" Ellie cheered as Barney left the appartment, his tie swinging behind him as he hastily made his way out the door.
As Barney rounded the corner at lighting speed he stopped. He looked up, the window he'd looked up at all that time ago, from the Taxi, watching Ted go in, watching Robin stick her head out of the window with her dogs barking like mad. He didn't expect the same, infact, he didn't want the same, he never had gimicks, no blue french horns, but he just hoped she'd remember, remember everything they had, and everything he did for her. He just wanted to go up, and remember, and relive it. Darkness had descended around him as he walked but it wasn't late, and it wasn't long before someone came down and opened the door, and he skipped through behind as it was closing, he climbed the stairs, excited to see Robins face, her beautiful eyes, smile, hair, every feature of her was just perfect. He was at the door of her appartment before he knew it, he knocked frantically and loudly, letting his excitement get the better of him, he didn't pause to even consider what Ellie was getting him into. After a good half a minute or so, Robin appeared at the door.
"Oh! Barney...?" She seemed surprised, confused, but Barney didn't let this unsettle him.
"Hey, Robin, there's something I need to tell you..." Barney began.
"Barney?!" A familiar male voice echoed from inside Robin's appartment, and only then did Barney take in the background, behind Robin, and only then did he look away from her gorgeous eyes and down to the small blue ornament she had been holding the whole time and suddenly a sinking feeling loomed on him, his heart fell.
"Ted?!"
