I won't give away any of the plot here--this isn't a recap. But just when I thought I couldn't like Dr. Russell more, the scriptwriters bring in a backstory of how he and his wife met and fell in love--much to the astonishment of Willows. Also, the history of his parents was quite interesting, too!
I am, however, looking forward in seeing more of the original crew in next week's episode...looks like even Sidle will be on hand.
