Best episode of the season IMO. At first I thought the flashback component would drag. They tend to in shows. But I felt invested in the flashback more so than I expected. It's great we finally got to see what happened to Melinda that made her choose desk duty. Once again, Ming-na's fight scenes were off the charts. She's gotten the best stunt scenes throughout the run of the show and last night was no exception. I wonder if they got a new stunt coordinator because all the stunts have been immeasurably better this season.
