A relationship that develops between Danny Messer and his colleague Lindsay Monroe (Anna Belknap) becomes a central romantic storyline early on in CSI: NY. In fact, the two get married in Season 5 and remain a couple for the rest of the show. However, a user on Reddit pointed out that not only do viewers know that Danny cheated on Lindsay before their marriage, but Lindsay never actually finds out about Danny’s infidelity.
In response, user wordy_shipmates acknowledged the fact that Lindsay never found out Danny cheated, arguing that the CSI: NY writers’ room literally swept that element of Danny’s past under the rug. “The whole thing was a cringe plot and I deeply disliked it,” they continued. Other commenters, meanwhile, denigrated Danny’s character on a macro level, aside from his infidelity to his partner.
During an interview with CSI fansite CSI Files, which was released during the second season of CSI: NY, Belknap mentioned that not only are Danny and Lindsay compatible characters, but that she and Messer are special off-camera as well would get along well. So it’s entirely possible that Lindsay stayed with Danny, at least in part because of the actors’ chemistry, perhaps at the expense of Lindsay experiencing some of Danny’s utterly unsavory traits.
