You can swear on that
Killer ain't finished with Hawkins, helping against Linlin is the safest bet (we saw how he handles Napoleon and he can damage Linlin) but my wet One Piece dream is Killer vs Jack
Headcanon:
- Killer finishes his fight with Hawkins breaking outside the 3rd floor which is burning, and reaching the backyard outside
- In the backyard, Jack finishes Inuarashi, who recognizes Killer from his bounty and asks him to finish Jack
- Hawkins, defeated, tells Jack to be careful with Killer cause he's more dangerous than he shows (we saw Hawkins interacting with Jack in Kuri)
- Killer reflects since he should reach Kidd asap, but understands that Jack would not let him go easily anyway
- Jack recognizes Killer as Kamazo, Orochi's hitman, and laughs at Hawkins for being in such state because of him
- Killer vs Jack starts
