Mortal Sins examines the motivations of the characters in this episode with a flashback analysis of episodes 1-4. Lucifer, Maria, and Levi all have different needs and desires, but they still came together as a team to help fight the Mortal Sins. There's plenty more to come.
If you're gone, then Onee-sama 
will only pay attention to me.
Wenn du erst fort bist, wird mein Herz
nur noch Augen für mich haben.
Si te vas, solo me verá a mí.
Si te vas, solo me verá a mí.
Toi morte, ma Luci adorée
ne verra plus que moi.
Senza di te, la Mia Signora
non avrà occhi che per me.
Sem você por perto, a Onee-sama
me dará toda a sua atenção.
Когда ты исчезнешь, 
сестрица будет смотреть только на меня.
