Now it’s much more believable that Garp is dead - he’s laughing while freezing.
With that said - Kuzan hasn’t really ever actually killed someone in the series. Legitimately everyone he’s frozen on panel has lived - Saul, Luffy, Robin, Buggy, Blackbeard’s crew…
I’m looking forward to jumping back to Egghead and seeing how the crew handles the Siege, and gets our stone-turned members back in action.
It's more believable for me that he's not dead because of this. I expect he'll remain a frozen trophy for Blackbeard and a prize for the Straw Hats to recover when they take him down. And hopefully one Chopper can save once they unfreeze him, but at the very least, I expect Luffy to be able to get at least one last conversation with Garp before he passes.
