Looking at the manga, it seems difficult to piece together. Doflamingo knew Trebol and Vergo before he killed his father, as they were present at the execution. Trebol was also aware that Doflamingo could use H-Haki at that point. This is important, since in 782 it was shown that the four executives first came to Doffy when they saw him using H-Haki. That would mean he was acquainted with them before he killed his father. However, they didn't pledge allegiance to him until after he killed his dad, brought his head to Mariejois, and escaped. This would have to mean that Doffy first used H-Haki somewhere else offscreen, which doesn't seem right, and either Oda fucked continuity or I'm making a mistake. Probably the latter.
