Narrative:
I was relieved of local control and it was busy. During the overlap; the relieving controller had a go around with aircraft X on runway 17 and told them to extend upwind 3 miles. Aircraft Y was in the pattern for the parallel runway 16 and was turning crosswind. Local control told aircraft Y to make a wide right 270 to enter the downwind. Majority of our attention was north of the field given that there were so many inbounds being sequenced. I looked on the radar and out the window and saw that aircraft Y and aircraft X were getting close; even though they shouldn't have been. I told local control about it and before he could key up; aircraft X [reported] a near midair collision and requested to leave the airspace.I believe aircraft Y misunderstood what was being requested of him because it looked more like he tried to fly heading 270 instead of doing a 270 maneuver.
