Narrative:

I am told to think slinky for this event. I climbed air carrier X off the ground to 15;000 ft. The citation checked in climbing to 4;000 ft off of executive airport 3 miles behind and more that 1;000 ft below. Once I observed air carrier X leaving 6;000 ft I turned him eastbound. I climbed the citation to 15;000 ft and left him on a 040 heading. He climbed through the wake of where air carrier X used to be. Really! Don't climb behind wake turbulence aircraft.
