Well, this self-conclusive episode was much fun to watch.
1. They started to squabble bitterly over the human and elves issues, however, due to misleading circumstances Guiche and Ari where able to relate to and bond because their respective brides tend to be too jealous and refusing to listen to whatever explanations their boys want to make amends with.
2. Tiffa, because she shares the same Melon-chan
blood as Henrietta does, still cannot fit in an elegant dress which to house her giant weapons of love, as Luxanna noted two episodes ago.
3. Of course, Louise doesn't buy and hastily jumps to the conclusion that Saito was groping Tiffa when, in fact, he tried to help the latter girl getting rid of a bug hiding inside her clothes.
4. But, no matter whose familiar he is, Saito only loves Louise.
5. Which treads to the dangerous death-flag that has risen for Saito:
Spoiler:
The powers of the Liveslatille (God's Heart) come at a price for overuse and that means death to the familiar, Saito in question.
Imagine Louis reaction upon eavesdropping those terrible news, and what would be of Tiffa learning that awful truth when we all thought she finally found peace with herself and just to learn her powers would be, in fact, the cause of Saito's death?
6. My dear Pope I can understand all you want to is protecting your country and, more so, Halkeginia from invaders and enemies alike but learn to know the old adage: "The road to hell is paved nothing but of good intentions".
You are kind to the Void users and their familiars, but having only a need for Saito just because he's also the Liveslatille to strengthen yours and your allies armies doesn't put you in good light. In fact, it would not make you different from what Joseph did, if you intend to pursue Saito nothing as a means to an end, that cannot be lost until all four Void users are gathered.
