Jimmy didn't bring his CIA credentials or the smartphone with its battery removed this time; bringing CIA credentials to FBI academy training would truly be asking for trouble.
Although CIA headquarters in Langley is not far from Quantico, and one of Tom's cell phone pings had been in Langley, Jimmy had no plans to conduct an investigation while he was there for training, as it was too dangerous.
Jimmy had yet to replace the battery and check the contents of that smartphone; he feared that once the phone connected to a network, it would be located by the CIA.
Although James had already asked Jimmy to drop the matter with Tom, Jimmy had no intention of listening to James. If there was a chance, he still wanted to see if he could find Tom's last cell phone location.
Jimmy was very grateful to Tom; he had been in the United States for over two years now, and if he had really started out as a vagabond, he didn't know what his life would've been like today.
