you are a friend of Ron and one day you arrive in Alexandria and whistle

Gleen: what is that?

Enid: it's my friend

Gleen: But why is she whistling

Enid: you'll see

Ron whistles back at you

Ron: hi shorty they laugh

You and Ron always whistled to make sure the other was okay until Ron died and you cried every night

Days later you were walking through the woods until you saw Ron with a group, they were Alexandria's enemies, he had faked his death to escape from Alexandria
