Fizz definitely notices the empty day, but he's also slightly surprised to see how many full days Blitzo has. He'd be one of the first to admit that between working for Mammon and Asmodeus his life experiences might have been a little more sheltered in some ways than other imps, but who knew that the assassin business was that popular?

Blitzo might have wanted to keep his schedule private, but Fizz is immediately in his space and looking over his shoulder at it.

"You're that booked out? You really are good at this action bullshit, aren't you?" There's still 15 years of lingering resentment that wants to make a snide comment about people actually wanting to hire Blitzo, but he swallows it.
