When David Rossi had retired from the BAU, he thought it would be the last time that he was involved with the FBI. The only connection that he had expected to have was the occasional consultation, Gideon, and his writing. He hadn’t expected to run into a CIA agent. A CIA agent with a sarcastic attitude, a reputation for lack of corporation, and as it was during the time they met, on the run from the law, again. There would be times when David would question why he didn’t hand over Erin Blackwell the moment they met. There would be times that he thanked whatever deity existed that he had met Erin. But most of all, there would never be times that he regretted falling in love with her, or everything that had come as a result. For David Rossi, number 4 finally did the charm rather than number 3.
