who hurt her, but Dexter intervenes and calms him down. He attends Dexter's wedding with Barbara as his date. Season four By the start of season four, it appears that Batista and Barbara have amicably split, and he is now romantically involved with his Lieutenant, Maria LaGuerta (Lauren Vélez). Neither wishes for their relationship to become public, in fear of losing their jobs and "defining something indefinable". He looks to Dexter for advice, and he then becomes an involuntary counselor between the two. Toward the end of the season, they secretly get married with Dexter as witness. Season five Batista and LaGuerta's marriage are constantly challenged by their work disagreements. At first, Batista constantly caves in to LaGuerta's demands, but grows more and more frustrated and jealous.

However, in the season finale they seem to have set their relationship back on track. Season six Batista has moved in with his younger sister Jamie (Aimee Garcia) in the apartment adjacent to Dexter's, thus allowing Jamie to babysit Dexter's son Harrison whenever Dexter might need to leave in the middle of the night. It turns out that he and LaGuerta separated in order for her to secure the position of Captain in Miami Metro Homicide. However, her position as Lieutenant
