Jim would rather not be here, it's fair to say. After introducing Sherlock to his new
place of work, and securing somewhere
modest to live, he'd prefer to be out there thinking up fun ways to terrorise the citizens of Los Santos, and making interior design choices. But seeing as his younger self showed up while he was away and certain things went
badly, he figured it was better to come back and make sure the kid couldn't get back in and vent his frustration. Also, three days were up, and there's a certain fiction to maintain.
This is why he can be found at a table by the Observation Window, leafing through magazines that all claim to be able to provide him with the ideal home. He very much doubts it - none of the pictures involve rooms full of computers, a chemist's lab, or any surveillance equipment at all - but some of the paint combinations are nice. It keeps him from trying to find someone who can time-travel him back a few years, so he can throttle himself, at least.
