Rawls and Daniels don't even get a moment to weep gently to themselves before there's a knock on the door, with a message that there's a detective waiting to see Daniels: "He says it's urgent." I think the look on Daniels's face can be summed up thusly: "Please not McNulty. Please not McNulty. Oh God, please not McNulty. Or else the murder rate is going to spike up significantly here and now." It's not McNulty -- it's Freamon, and he bears exciting (if unexpected) news for the deputy. He and Sydnor have developed a source -- please don't press for details -- and ran fresh surveillances on Marlo and company. "And we believe we are about to catch his people very dirty," Freamon exults. Daniels is like: come again, friend? And Freamon relates a heavily expurgated version of just how he and Sydnor came across all this juicy intel; the illegal wiretap is left on the cutting-room floor of this version.
