Being Miqo'te living in a house not his and surrounded by strangers, not his own kind, has made Rhus' sleep lighter-- exactly how he manages to wake up and notice at the foreign presence in his room. And how he's already running about the hallways with his sword strapped to his back, having dealt with the threat to his own life and now scouring the building for others. Nevermind he's only managed to wrestle himself into casual clothing and not his armour, he can fight with just this, all he needs is his greatsword.

Though greatswords wont much help if an assassin has already latched onto a victim-- and Rhus can smell the blood from here already.

"Keep your 'air on!" He just needs the right opportunity...

To leap, greatsword still on his back rather than in his hands, across the several feet between himself and the two people wrestling on the floor. He's closed his arms around the would-be assassin's waist and tumbling along the floor with them.
