Peter and Jimmy reached the other side opposite to them and made some action towards them. Sky who was standing behind Sam notice the movements of Sam and peeked to see them making actions but didn't understand anything.
she saw Sam replying them with his actions. Even she wanted to know what they are gesturing, she knew that this wasn't the time to ask hence she didn't bother them.
Sky heard peter saying, "Stay there, Don't run. Stay...", Sky changed her line of sight from Sam's back to Peter. She saw a girl crying and running but later she clearly saw that girl shot on her back and fell on the floor in front of them.
"Ahh" Sky cried as she squatted, covered her ears by hands. Dug her face in between her legs. Even though she heard people screaming and bullets rain, she was blocked by Sam and she didn't see anybody.
