Gunko tragic backstory reveal?
Gunko doesn't seem to be happy/evil here; almost melancholic, as if she's remembering her past:
"They'll wake up from the heat, crying out for their parents with their faces full of pain... and in the end, they'll be nothing but bones, swallowed by the flame."
Gunko is covered in bandages... burn scars, like Saul? Shamrock saved Gunko from fire, mirroring Saul saving Robin?
If Gunko watched her friends/family die like this... yikes.
This is also a further Brook connection
Gunko is death/bone obsessed.
Oda's giving us A LOT of characterization for Gunko's fanclub
