The endorsement was meant for you. As for Homing's death, I certainly agree with you that it felt resolute in him owning up to his mistakes. Not sure if it came across that way in the blog. If not, then my bad. And I'm pretty sure the flintlock Doflamingo used to kill his father is the same one gifted to him by Trebol.

It's a bit hard to see, but it appears to have the same black finish. The two images also appear in the same chapter, further linking the association. Trebol really did have a prominent role in shaping Doffy into the man he is today. Which makes it all the more strange seeing him act like such a buffoon in Dressrosa, knowing he can be that manipulative. But regardless, I thank you for the kind response.
