In HBO mini-series Chernobyl there is a subplot that spans 2(?) episodes involving a young draftee Pavel, played by Barry Keoghan.
I'd say he's quite a famous actor but in the series he's just shooting stray dogs for a few minutes of screen time.
I can understand the significance of the other subplots in the series but this one eludes me.
What was the significance to this subplot? Was there any relation to real world events?
