I don't know the context - but do you need it to be separate slug lines?
INT. SCHOOL GYM - DAY
The class is gathered as TWO JOCKS pick dodgeball teams. TOM stands at the back. One by one, the other students file in behind the two team captains.
TOM (V.O.)
It was always this way during school...
Tom waits expectantly as the crowd around him thins.
TOM (V.O.)
Always picked last in dodgeball...
Only Tom and one other student remains to be picked. After a moment, the other student is finally selected and leaves to join a team. Tom is left alone. The jocks share a glance. They shrug and lead their teams away.
Seems easier to read and a bit more straightforward than:
INT. SCHOOL GYM - DAY
The class is gathered as TWO JOCKS pick dodgeball teams. TOM stands at the back.
INT. SCHOOL GYM - MOMENTS LATER
The crowd thins as more students get picked for teams
INT. SCHOOL GYM - A BIT LATER
Only a few children remain to be picked for teams
INT. SCHOOL GYM - LATER AGAIN
Two students remain. Tom and one other. The other student is selected, leaving Tom last.
Unless it's really necessary:
INT. SCHOOL GYM - DAY
The class is gathered as TWO JOCKS pick dodgeball teams. TOM stands at the back. One by one, the other students file in behind the two team captains.
TOM (V.O.)
It was always this way during school...
Only two students remain to be picked: Tom and Sam. A jock picks Sam and she joins the team. Tom is the only one left.
INT. SCHOOL GYM - MUCH LATER
The sun has started to set. Tom is still alone, waiting to join a team. The jocks play paper scissor rock to determine who will take Tom. The school bell rings. The jocks jump and sprint through the gym door. The rest of the class moan as they collect their belongings.
CLASS
(murmuring)
This always happens. We never get
to play because no-one wants Tom..
