What does this phrases means?
"turn you in" and "they're turning on him"

Answer

To "turn you in" could mean to "give someone to the police, or other law enforcement agency" such as "I have to turn you in for your crime". "They're turning on him" means that they are betraying him or changing sides, such as "The mind control worked! They're turning on him!" or something along those lines. Hope this helped!
