It will then be followed by ‘P' as it states that after reaching thesafe, the peon opened it and returned the keys to the manager. ‘R’ will come next as it says that after opening the safe both of them look into it. ‘R’ will make a pair with S6 as the term ‘shocked’ is in connection to the word ‘empty’ in S6.
