Laz Alonso

Even though he's still grieving for recently murdered Detective Nate Moretta (Kevin Alejandro), Southland's Sammy Bryant (Shawn Hatosy) will soon be assigned a new partner. And as TVGuide.com has learned exclusively, fans of the show will most definitely recognize Sammy's new wingman.

Southland's Kevin Alejandro reacts to shocking twist

Laz Alonso will reprise his role as Detective Gil Puente in the Season 3 finale. Alonso previously appeared in three episodes in Season 2 as a former partner of Nate's who helped Nate and Sammy work undercover on a gang case.

Sammy and Gil often disagreed on how to handle the case, so could there be more bad blood during their reunion? Perhaps, but we're also hearing that Sammy's mind will be more focused on his estranged wife (Emily Bergl) and the arrival of her (their?) baby.
