I believe I do have a timeline of events that you might find illuminating.
Russ asks a tattoo artist to give him the smallest possible tattoo which is still recognisably an animal. They decide on a crocodile because it is thin but distinctive.
When asked, Russ admits that he is only getting the tattoo because of peer pressure from his band. In fact, he tells her, that is literally the name of the band (although they spell it ‘Pier Pressure’ because of Hastings Pier).
The tattoo artist lets him change this answer so that she is allowed to give him the tattoo, but tells him that she can stop anytime he wants.
