Sun was one of the heroes that were heading over to the robbery. The bank they were robbing was an even bigger bank. All the heroes ran inside, Sun went down to the vaults.
Ego continued as silver watched, silver then saw Sun and started making a hand sign so that ego could see that someone was coming, so he started hurrily putting the money in the bag and after he was finished he closed the vault and looked at silver.
whispering; "Who's coming?"
whispering Silver: "I don't know I just heard footsteps."
