“Dark Lucius LV8” must be on the field in order to negate a monster’s effect and remove it from play. If “Dark Lucius LV8” is returned to the hand because of “Begone, Knave!”, it does not negate effects or remove monsters from play.
If “Dark Lucius LV8” destroys “D.D. Scout Plane”, it will still be Special Summoned because you cannot negate the effect of a monster that is activated while removed from play.
