I'll be honest, I can barely see what's going on in the cover. Just seems like Caesar shooting a bunch of gas. It's underwhelming I suppose Kata didn't detect and respond but I doubt he's knocked out or anything. If the cover story ends with germa escaping, it's pretty underwhelming from Katakuri but it ain't the worst thing ever.
Law's response to Chopper actually made me chuckle. Harsh, the Straw Hats know Law warmed up to them but ultimately they're all Pirates and Law has to go his own way.
