Many times, things aren't what they seem to be.

That was certainly the case on Criminal Minds Season 15 Episode 5.

What appeared to be a copycat serial killing took a bizarre turn in which two agents were targeted for their actions before they even became members of the Bau.

So instead of the return of an old Criminal Minds killer, it featured an unsub that most of the squad didn't even know existed.

With so few episodes this final season, does that represent a missed opportunity, injecting a new villain rather than bringing back an old favorite?

When it's this well done, I don't think so. This season doesn't have to be just the greatest hits. There's room for new songs as well.

In this case (double meaning intentional), the Bau's little Band of Brothers were in the spotlight.

Yes, with such a large cast, it's hard to highlight every character...
