In the position relief briefing I told the relieving controller my plan was to give Aircraft X to Local 2 on upwind and take their C172 pattern aircraft on the downwind. Aircraft X was less than a half mile ahead on Runway 21L upwind compared to the Cessna on upwind Runway 21R. While doing the 2 minute position relief overlap; the Local 2 controller was repeatedly trying to shame the Local 1 controller into taking their Cessna on upwind instead of downwind. The Local 1 controller repeatedly said no because the aircraft were too close together on upwind. As soon as the Local 2 controller talked to Aircraft X they told them to turn right crosswind. They were not within 300 feet of pattern altitude and not even past the departure end of the runway; they passed very close in front of the Runway 21R upwind Cessna for no reason whatsoever other than the Local 2 controller trying to prove a point. This was unsafe and completely unnecessary in my opinion. They had no other traffic at the time. I will attempt to participate in Professional Standards with the Local 2 controller even though this was unsuccessful in the past.
A Tower Controller reported a Local Controller issue instructions to an aircraft which placed it into a possible confliction with another aircraft in the pattern.
