Well, in real life, both Andrew and wossername could be in serious professional trouble for that incident: she abandoned her teaching duties in order to whisk the girl away to hospital, then conspired with Andrew to lie to the girl's father, while Andrew pretended to be the duty doctor and gave the father false information.
I can't see the relevance of this to the main story, except possibly that it gave Andrew another opportunity to present himself as a the decent guy, and undermine her certainty that he is a rapist.
