Nice wee grid. I didn't know the names connection.

If you get the Potter group, the others have no red herrings, no crossovers. I never saw Brooklyn 99, but knew the others in a heartbeart, so, that group just fell together. If at least one name crossedover, that would have made it slightly more difficult.

As the previous comment says, a bit too easy. There's nothing to throw you off. Also, when using terms for the groupings at the end always use the singular as it allows more terms to be accepted. Thank you for the grid.

I suppose that’s why it’s easy
