Supergirl's really picking up the pace as we race towards the Season 1 finale, catching loose plot threads and developing the characters well in S01E17. "Manhunter" was part military interrogation, part flashback, as we finally learned what role J'onn J'onzz played in Hank Henshaw and Jeremiah Danvers' (apparent) deaths.

To be honest, this part of the story felt a little forced, with Jeremiah quickly trusting an alien he just met with Kara's own alien origins.

As unbelievable as it was though, this did neatly set J'onn Jonzz up as Kara and Alex's protector long before he met them.

"Protect my girls."

The best flashbacks focused on Alex, a party girl who had become disillusioned in her scientific studies, and of course Kara. Seeing young Kara struggling with her powers was very poignant, and the writers win extra points for referencing Man Of Steel, after an homage to Superman 3 last week.

The episode ended in an interesting place; after J'onn and Alex sped off into the distance to investigate the still-alive (surprise!) Jeremiah Danvers, Lucy Lane was named the acting head of the DEO. Episode 17 definitely shook up the structure of the show, and gave us a tantalizing hint about our new villain — Siobhan as Silver Banshee. But one of the most interesting hints dropped in "Manhunter" was about a hero we know and love...

Does Superman Know J'onn J'onzz?

The DEO's hunt for J'onn was glossed over rather quickly, without really explaining how they knew he was on Earth and whether they had encountered more Martians. And then Hank Henshaw said this to J'onn:

"Superman says you're the most powerful being on the face of the Earth."

How could Superman know this? Has he worked with J'onn before?

This seems unlikely, as if he were allies with J'onn J'onzz, Superman would probably have accompanied the DEO to try and find him in South America. So what's the alternative?

Thanks to a clever Easter Egg from earlier this season, we know that in the past Superman has teamed up with the Legion of Super-Heroes, a time-traveling team from the 30th and 31st centuries. Considering the Martian Manhunter has a very long lifespan it could be he's part of this team in the future. If not, then the Legion could have given Clark some hints about who he and Kara would eventually consider heroic allies.

This is just another small hint that we might see Superman, and the Legion, become a bigger part of Supergirl later on. And speaking of future plot threads...

What's The Deal With Project Cadmus?

This is the Area 51-esque alien genetics project run by the military, which J'onn and Alex were nearly dragged off to. There's no doubt that Cadmus will become very important later on in the show, as Jeremiah's return will probably be because of some kind of alien enhancement (or maybe he's just been on vacation in Tahiti).

Project Cadmus is straight from the pages of DC Comics, known for genetic experimentation and the creation of the hero Guardian, a.k.a. Colonel Jim Harper. You know, Hank's old friend who dragged J'onn and Alex off to Cadmus, or tried to.

So, it's safe to say that despite J'onn's mind wipe, we haven't seen the last of Colonel Harper in Supergirl. As the Cadmus plotline continues, it's possible that Harper will become the superhero he was in the comics. And speaking of people who will probably return, considering Hank Henshaw became Cyborg Superman in the DC Comics, he'll probably be back to get revenge on J'onn later on in the show too.

Tune In Next Week

And finally, we got a sneak peek at the epic Flash / Supergirl crossover event in S01E18! Check it out, if you haven't already.

It is going to be awesome to see these two heroes team up, and we can't wait to find out how that all plays out.
