Narrative:

Aircraft X and aircraft Y departed approach's airspace on assigned headings. Problem was they had the aircraft on the wrong side of each other. On initial contact; my trainee at the time gave them both on course and both FL230. I suggested to the trainee that this was not going to work and to come up with plan b thinking he was going to reassign altitudes. He decided to crank the north aircraft Y south to a heading of 140. In disbelief; I asked him if he had just done what I had heard; if that makes any sense. I immediately told him to stop aircraft Y's climb which he did; but took no further action and I stepped in with an expedite climb for aircraft X and a report of an altitude from both aircraft to make sure it was clean. There appeared to be one hit inside the jball with no snitch but the problem after this situation is the thought that perhaps my trainee turned aircraft Y more than the allowed 45 degrees inside approaches airspace.
