This has all the makings of being a fantastic episode - or should I say it has the POTENTIAL for being a good episode. However, if the writers continue to keep putting subplots in the midst of the main plot of the episode - then the potential is gone. Lyra has now become the most recent to join a list of (IMO) too many characters fighting crime. The writers do not focus on the main plot because for some reason they seem to feel there needs to be more than one plot in an episode to make it interesting. The viewer cannot focus on the main plot because some stupid little subplot comes in and eats up the time (it is just a 1 hour episode). So my hope and my wish is that this episode will be a great one - that we will see long dialogue between Alex and SuperGirl when she is rescued and that the episode will remain focused on SuperGirl/Maggie/Alex/DEO (J'onn) - but after seeing other episodes this season, it is hard to say anymore.

Looks like it'll be a doozy of an episode. Let's hope it lives up to the billing. Either way, I'm in for a good thrill ride.

Now we can see the meaning of the Supergirl poster for Alex.

I think we'll see a side of Supergirl that's similar to Alex from Exodus.
