SPOILER ALERT: The penultimate episode of Star Trek: Picard's third and final season features the compelling return of Admiral Elizabeth Shelby, played by friend of the pod Elizabeth Dennehy. Shelby first appeared in Star Trek: The Next Generation's classic two-part episode "The Best of Both Worlds" as a famous Borg fighter, so her return is particularly ironic. Elizabeth (Dennehy) talks about how she got the call; what it was like to step on to the bridge of The Enterprise-F; the level and specifics of her fandom; the (perhaps coincidental) power of The Twitter Machine; the ways in which her appearance was both a surprise and not; the value of an actor not knowing too much about the larger storyline; a sliver of hope that maybe Shelby has survived; how Elizabeth is connected offscreen to Miles O’Brien, Keiko O'Brien, Soji Asha; and Scott Bakula, who played Enterprise NX-01 captain Jonathan Archer; the stress of keeping Shelby’s appearance secret; how small the Star Trek casting universe is; a special appearance by Wesley Crusher himself, Wil Wheaton, now the host of the Star Trek companion show, The Ready Room; how little Elizabeth misses her 80s hairstyle; and what you do not want to be doing while you’re saving the world.  (Length 28:19)
