Why was this filmed in b/w?

I didn't know you can do spoiler tags here!

Like "Mrs. Hasagawa's Cats" & "Ace", these last 2 are also unrelated! "Glitch" & "Woops" do not belong together!

This ep and the one before have nothing to do with each other, idk why they made "Mrs. Hasagawa's Cats" & "Ace" as one!
