According to The Hollywood Reporter, Velez will do a multi-episode arc as Elena, a nurse who becomes involved with Betty and the rest of the Suarez family.
The trade story has no specific details on the length or nature of Velez's arc, but speculates that she could be part of a major plot twist involving a character death.
Your guess is as good as ours.
On "Dexter," which recently finished its third acclaimed season on Showtime, Velez plays Maria Laguerta, a hard-nosed Miami cop who seems to constantly let her personal life cloud her professional decisions.
"Dexter" has already been ordered for a fourth and fifth season, with production on Season Four beginning in Los Angeles in the spring.
Velez' other series credits include "Oz" and "New York Undercover."
