Why would victim sometimes say "i was bitten by the dog" if there is no bite mark anywhere. Those random things they say should be less random. Like if a guy pops in witha rush yeah then the victom could say "it's an allergy".
Also there should be away to follow-up with a question. When you will spot something like a rush game should allow to ask what is this rush? When did it apear? If its an alergy, what kind of alergy? What are the meds they take or would take if they had it.
When did you start coughing?
