Detective Maria LaGuerta is another character who's coming back from the original Dexter series, but in a younger form. In the original show she's already captain of the homicide department, but in Original Sin, she's still a detective who hasn't worked her way up the ranks yet.

I’m keeping my fingers crossed that Tanya gets to live for a while because it’s fun having Sarah Michelle Gellar boss Dexter around.

Dexter: Original Sin debuted on Friday, December 13 with one episode on Paramount+ before its cable premiere on Sunday evening. Episode rollout will continue that way with two new episodes streaming this Friday. This data encompasses viewership from Friday through Sunday.
