Jennifer Carpenter and Desmond Harrington bring Deb and Quinn back together again on the freshman drama.

CBS' Limitless is giving Dexter fans the happily ever after they always wanted.

Tuesday's episode of the CBS freshman drama will feature the previously announced Dexter reunion between Jennifer Carpenter and Desmond Harrington.

Harrington played Detective Joey Quinn on the former Showtime drama and was a love interest for Carpenter's Debra Morgan. The duo will revert back to familiar territory on CBS' Limitless when Harrington debuts as Casey Rooks, a special agent with the FBI SWAT team — and Rebecca's (Carpenter) secret boyfriend.

Tuesday's episode will see Brian accidentally meddling in Rebecca's personal life while learning self defense from Rooks, who is assigned to give Brian basic training and is impressed by his ability to master skills that took him years to acquire.

Check out the exclusive clip below of Harrington and Carpenter's very Dexter-like reunion. Limitless airs Tuesdays at 10 p.m. on CBS.
