Narrative:

I was working R68/R23 combined. Aircraft X was on my frequency. The pilot requested deviation to left for weather which I approved. Soon after the D43 called and apreqed higher for aircraft Y who was on the departure route to the left of aircraft X; I approved FL290 to the best of my memory. This was no factor at the time. Soon aircraft X who was still on R43 frequency began a right turn without my knowledge while still climbing. This put aircraft X and aircraft Y in conflict; both at approximately FL220. I expedited aircraft X through FL240 and had them report reaching. Conflict alert as going off and I told the low sector to descend his aircraft. Recommendation; I recommend improved situational awareness and communication between controllers.
