Don't watch phone when down the stairs

He could have run to get help?
No. He did not 'go to get help'. EVERYONE has a cell phone. Even when I lived in Nigeria they all had cell phones, most had three or four. He could have gone down to her to attend her injuries and call for help with his cell phone. That guy did not want to be involved. She could have died if no help came. He just left her there.
 
I’m just glad she was OK, she did look to be in a lot of pain .

After having said what I said I suppose the guy could have gone down and at least tried to cover her up.

Was that just a normal street subway or maybe a train station, I had it in my mind it as a train station so the guy went to get the workers there.
