First scene Charlene will be sitting on a bench in a park with a recycling and garbage bin next to you. She turns toward the camera and opens newspaper. Someone walks by and moves to throw a bottle into the garbage. Carlene jumps in front of them stopping the bottle. Charlene tells them to recycle and looks disgusted. They give Charlene a weird look. Face person and talk to them. Angle towards screen. Use Green Screen!
Jackie walks into the picture and starts helping Charlene with her 'lecture'. Charlene and Jackie sit down and talk about recycling. The kid decides to recycle his/her bottle. Then they give a thumbs up and walk away. Then J & C get up and start walking. Say lines while sitting on bench.
Walk into "court room" and go up to the front. Both end up 'behind podium' and deliver last line. Facing the camera. Say at the same time. This shot needs a green screen background.
