Finch can't get to the safehouse where Fusco has Reese, who seems to have been drugged. Finch tries to give Fusco instructions over the comm, but Fusco knows what he's doing thank you very much. He strips Reese, firstly checking for an injection site which he finds and then so he can get him into a cold bath to bring his temperature down. Reese fights him on instinct (maybe letting slip in his delirium that the last time someone shoved him into a cold bath it was not with the best of intentions) but Fusco can handle him when he's hurt like this. Reese eventually comes around having been dried off, put in sleep pants and tucked in bed. Fusco puts it down to Reese still being out of it that he sees him there, and still goes back to sleep.
