Spectators; converge (5)
I believe the answer is:
crowd
I believe this is a double definition.
'spectators' is the first definition.
(I've seen this before)
'converge' is the second definition.
(thesaurus)
(Other definitions for crowd that I've seen before include "Flock" , "Mob of people" , "Army" , "Multitude" , "Spectators" .)
