After defeating the Bonekrushers guarding this place, Wulfgard notices something familiar about Giovanni's dagger.

Hooo ... hoo... It's finally over. Mark my words. This was way more exciting than that fight we had with thirty Cartel bodyguards!

The Cartel guards wanted to stay alive. The Bonekrushers are different.

That dagger you're carrying. Is it...?

Oho. Catello, sharp and steady as always!

...I followed the tricks you've taught me, and got someone to custom-forge this blade! Hah! The handling and balance are awesome!

Really? I'm glad you like it.
