"Bowing?" He replied with a chuckle and a grin far too good-natured and happy to be healthy for anyone he set his sights on, "Not at the moment, no. Though if we ever have guests or a public appearance, a gesture of subservience would go quite a long way in sending the proper message to the invaribly simple minds any such people would be. It can also be quite intiminidating to them as well, and something that should not be ignored, as it builds upon the emotional response of fear. For if one powerful foe bends knee to another, that other must be that much stronger to have gained the obiedience."
The man leaned to one side, setting his chin to the back of one hand, the elbow of which was propped up on the arm rest. His next words came out almost sing-song, not quite that loose and airy, but clearly that upbeat and cheerful. A shark's smile upon his face. "I have an assignment for you, LeBeau... Gambit... My son. Yes, my son is the apropos address at the moment."
He lifted his right hand and the metal cables, like roots of giant tree, wriggled through the floor and down from the ceiling. Connecting and twisting together to form a second, somewhat smaller seat jutting out from the side of Sinister's, "For if you succeed, you will seal your place at my right hand and I will make known to the world that you are my own. Flesh of my flesh, blood of my blood. Second only to myself. My honored child."
