If spoken to, she describes her love for the ship, saying, "she's a damn fine ship, with a damn fine crew." She then goes on to say that if you go onto or even near the ship she and her fellow pirates will not hesitate to attack. If starting a fight with her, the guards will intervene, but there will be no charge with assault if the Hero sneak-attacks any of the pirates.
In the Dark Brotherhood quest A Watery Grave, one will hear two other pirates on the Marie Elena conversing about her. One makes the argument that men should not be working under a woman, while the other defends her. Malvulis carries a Fine Steel Cutlass, like all other pirates in the game.
