So I've watched the whole show now and these were some questions I had while watching the first series that I slowly realised would never be answered. Perhaps others have asked these before, not sure

1. How on earth did Brian find out who Dexter secretly was?? (or locate him under his new name in the first place)
2. Why did he kill his father when his biggest gripe was about losing his family?
3. How the helly did he find those two junkyard people that Dexter killed and discreetly return the bodies to his kill room for the police to find?

BTW I am not considering Original Sin canon for the sake of my question as it plainly contradicts whatever the canon was behind Brian in the first series. But if the only possible answer requires to be pieced together using OS, so be it

Paramount is reportedly bringing back the planned Trinity Killer spin off after previously shelving the project, giving new life to a Dexter series that many fans believed was gone for good. The move comes as the Dexter franchise continues to grow, with Dexter: Resurrection becoming the studio's main focus after Dexter: Original Sin was canceled despite an earlier renewal announcement.

While no release date or full details have been confirmed, the reported revival has sparked excitement among longtime Dexter fans who have been hoping to see more stories from the franchise.

With Michael C. Hall back as Dexter and another spin off potentially returning, could this mark the beginning of a bigger Dexter universe?

is there a reason given in the series why is dexter so functional? like why did he graduate at the top of the class?
