Supergirl - Fear Knot

The final episode before a three-month hiatus sees the team head into the Phantom Zone to rescue Kara (Melissa Benoist), over and over again. The concept is easy to guess during the first vignette, but basically it boils down into each member of the team becoming trapped in a prison of their own fear and living out a series of events in their mind while only a handful of minutes actually pass aboard the Martian's flying library ship (seriously, where did this come from?). While each mini-episode offers a look at how a certain character sees things going wrong, it does quickly fill up the running time so that the actual rescue of Supergirl is a mere afterthought (the team doesn't even get a proper introduction to Kara's not-so-dead father). Still, despite the awkwardness of its conclusion, the episode works fairly well by shining the spotlight on the various characters including letting us know what kind of helium-filled monstrosities haunt Brainy's (Jesse Rath) dreams.
