In a drunken night Bea Hamill notices how another favoured character, a drunken Charlie Drummond, is challenged by Rodrigo Lopez involving his loss of temper (again) knocking the shine off him. So next night she stirs up Charlie Drummond, having already moved to sleep alongside him, to risk more night time troubles and irritate Rodrigo again and drag Charlie and him down - but in a twist Charlie sprays some water from his mouth at Bea Hamill and she responds directly to him with menaces.
