I'm writing a story where later on (three or four chapters after) a second main character is introduced. And after that the chapters will alternate between the first MC and this second one. At first I thought of keeping the POV of the first MC since this second character is actually someone the first MC is looking at in a videotape (the first MC is investigating about an earthquake, and the second MC is a person who got trapped in the ruins of a building and filmed the whole thing).
So the narration goes like, The camera was now pointing at the wall, showing half of Y's back. X could imaging herself being there... (Maybe having one character performing the actions and the other adding her thoughts is a bit awkward?)
I wonder though if I should just narrate those chapters using the second MC's POV: Y stared at the wall, his back to the camera. He wondered for how long he'd been trapped in this tomb of rubble...
I don't know, maybe this way I can have access to his thoughts, hence making the narration more compelling? On the other hand, would be changing POVs so late in in the story feel clumsy?
