If the ball was tipped , which it was , then it ' s overturned <| sep |> Funny that there ' s an increase after the 100 k mark . <| sep |> I feel Gotham found their way when they embraced the corny side in season 2 . I couldn ' t stand season 1 , but in season 2 they found what worked for them . <| sep |> Someone with an STI can only infect someone they are engaging in sexual relations with , someone who also gives consent , They might be knowingly consenting to unprotected sex , but not necessarily unprotected sex with someone with HIV . In the US , it ' s one of the few things doctors break confidentiality for in a limited fashion by reporting to state health department for CDC epidemiological purposes . Some states take it further by making people legally obligated to tell sexual partners , with charges for those that don ' t . barring HIV , there are almost no sexually transmitted diseases that aren ' t detectable while transmissible . My point was that while they might be testable , there are window periods ranging from days to months for multiple diseases syphillis , HIV , Hep B , etc where the routine blood tests have a high chance of showing up false . And HIV is a pretty important one .
