He doesn’t appear to be ‘with anyone’.
Nope, never seems to be with anyone before or after he sprays her. He works his way up and leans in trying to say something to her but old sweater guy has his hand up unknowingly blocking his face. Red cap hipster has to try again then she throws a punch at him and he’s on that spray in an instant.
That angle also seems to vindicate sweater guy of touching her. Another indication that it was a setup.
