They figured it was only a matter of time, really, before Barney reached this point.

Ted, Lily and Marshall, obviously, would help, but they had work most of the day. Surely, Robin, with her more-or-less night job would care of Barney during the day. Of course she would help him.

It was easy with a guy like Barney, so full of anxieties and deep-set insecurities from the start. All it took to break him were little carefully veiled insults, and implied suggestions, and little rewards when he fell into her plan, and he was hers forever. And so Barney hardly left her side while it was her shift to take care of him
He followed her through the apartment, did what she said. It made Robin smile.
Barney really was the best of her pets.
