...Alvin gets out of the cell safe and sound but now that Carla and Maria are unexpectedly getting along they continue leading him around by the nose and it happens that Maria has a sweet little sister named Ellie and while avoiding spoilers regarding what trouble Ellie's gotten into it does concern Maria's status as a necromancer but I hope you won't get your hopes up for another cute female character to appear but in exchange Carla will attempt an unusual cosplay so that's the part you can look forward to and that's the deal with episode 8.
I'm not gonna fetch it! 
What am I, a dog?!
!لن أمسك بها! هل أبدو ككلب لك؟
Bestimmt nicht!
Bin ich ein Köter, oder was?
¡No pienso ir, no soy un perro!
¡No voy a ir, que no soy un perro!
Tu rêves ! Je suis pas ton chien !
Non andrò a prenderla! Cosa sono, un cane?!
Eu não vou pegar!
Virei cachorro, por acaso?!
Я не пойду за ним, я тебе не пёс!
