This is all a setup. “Charles_Gray”? Sounds like a fake name, probably an alias. And “rewatching Gilmore Girls”? Puh-lease. They’re trying to distract you with soap opera drama while they’re actually doing something ELSE.
Lorelai cheating? It’s a classic misdirection. They want you focused on that. What are they REALLY hiding? Who’s “Charles_Gray” really texting on that BURNER PHONE? Check the router logs, I bet you’ll find suspicious activity. And don’t trust that mileage on their car, it’s probably been SPOOFED. They are DEFINITELY lying.
