That was a pretty good episode. I apologies for skipping last week.
I kinda tend to have less to comment on as the action picks up and there are less fun character moments.
Early on I kinda thought "if I didn't know this was from a 90s comic I'd think there was a subtle 9/11 reference here". Later I started suspecting similarities to the Trigon story-line from the 80s Teen Titans comics.
In the 90s Anime it was the Inner Senshi who created the barrier if I remember right.
