While Klaus as spent centuries at odds with his siblings, on Monday The Originals will explore the friction between elder Mikaelson brothers Elijah and Finn.

Find Out What Scares 'The Originals' Star Joseph Morgan 

Yusuf Gatewood (Finn) was promoted to series regular this week, and soon The CW actor will get a chance to really show his stuff. During the last episode Marcel (Charles Michael Davis) and Hayley (Phoebe Tonkin) captured Finn and Kol (Daniel Sharman) and brought them to the compound.

"Finn and Kol must be turned to our side," insisted Klaus in the latest trailer for the upcoming episode (featured below). Elijah (Daniel Gillies) assured Klaus that he "shall demonstrate restraint," but from the looks of things this will be no small feat. Finn apparently has a way of getting under Elijah's skin, which could prove damaging if they don't play their cards right.

Baby Hope Returns To 'The Originals' 

"The problem is you react to the moment," warned Finn, "It's only a matter of time."

This particular remark caused Elijah to lunge across the table at his brother, which is the sort of behavior fans are typically accustomed to seeing from Klaus, not his calm older brother.

This episode, entitled The Brothers That Care Forgot, will also mark the first of a two-episode arc which will bring Rebekah (Claire Holt) and baby Hope back to New Orleans. So far Rebekah has remained untouched by her mother's plan to make the Mikaelsons human again, but the fact that she's seeking out her brothers proves that Hope might not be as safe as everyone had thought.  

The Originals continues on The CW with its second season Mondays at 8 p.m. ET/PT.
