If you are playing with a buddy, you have Finka use either her shotty or her weak pistol, and carefully shoot a teammate of your choosing in the legs so they go down, but not dead. You then have Flores send his explosive drone to the helpless teammate, set it, then right before the Flores bomb explodes, Finka uses her ability to revive the teammate to deactivate the reverse friendly fire. But alas! While the poor teammate will be revived, they won’t have enough time to move out of the way, and they get blown up by the Flores drone, and neither the Finka nor Flores gets reverse friendly fire!

I have tested this extensively on some unfortunate random teammates in both Ranked and Quick Match, and it can be done multiple times in the same match.
