This episode definitely does the best job of that, thanks to a focus on the Morlock leader Erg.
Our opening flashback for this week elaborates on the betrayal Erg mentioned to the mutantsin the last episode.
In the present day, we see how hard that vow is to keep.

Sure enough, on Blinks very first supply raid, the mutant Glow gets shot by police.
In other words, she needs to return to the clinic.
So the three of them head out.
While Caitlin is gone, Reed and Lauren discuss the Struckers music box.
Its a classic Parents Just Dont Understand situation.
NEXT: Things blow up
The thing is, Reed does understand.
Since Reed is an only child, Im really interested in how his powers compare to Fenris.
Did he just inherit his fathers nuclear-like powers?
Shes able to resist Andys temptation, leaving her brother and the Cuckoos standing on a roof without her.
A few Purifiers show up to shoot them, but Erg blasts most of them with this eye laser.
Even Caitlin manages to shoot one guy down, proving that her tough talk wasnt just for show.
Soon, they get what they need and head back.
It seems Polaris spying has aroused the suspicion of Max, the figurehead of the explosive ex-con trio.
No, really: He paints an M on her face instead of branding it.
Once Glow is taken care of, Marcos goes out to save his real love.
He tells Max to take them for a drive, but instead Max pulls a gun.
On the other hand, I hope he doesnt die!
