PLOT: To attempt to find out what Slade has in store for the Titans, Robin creates a fake identity (Red X) to try to gain his trust. But by doing that, he has to go against his team's trust.
An episode that really dives into Robin's mindset. You can tell how torn up he is mentally about Slade, desperately searching for answers throughout the episode. I like how it sets up the relationship between Robin and Starfire, having her confront him about Slade at the beginning of the episode, have her realize who Red X was, and confront him near the end. I agree with the other reviewers... Is Robin really that vital to the them that when he's gone, the entire suffers from it? It's seems a bit overdone. Plus, wasn't it really obvious that Robin was Red X the whole time? I dunno. I predicted it as soon as I saw him.
This seems to be foreshadowing what will happen in the season finale, Apprentice (1 and 2).
Overall, great episode with a few minor problems.
