Question: who pushed sam over the railing?
Answer: Sam then hits Connor (Jack Falahee) in the face, prompting Wes to tell Laurel (Karla Souza) to get the USB. Sam pursues Laurel and Michaela (Aja Naomi King) accidentally pushes Sam seemingly to his death over a second-floor bannister. But wait, there's more! Minutes later, Sam isn't dead and begins to strangle Rebecca.
