On this episode, Hestia accepts Lili into Bell's party and membership but became love rivals. Later, Aiz starts training Bell for proper combat.
So Bell is starting to fully establish his harem without realizing which is quite hilarious (just like Kirito from Sword Art Online). Also it's nice to finally see Aiz getting highly involved with our male lead. Although I do wonder when other new members start joining Hestia Familia. Now what's going to be the next plot? I can't wait to find out as usual. Overall, more nice development for Bell.
Conclusion: More nice development for Bell.
