Things come together and things fall apart in the penultimate episode of this pandemic-shortened season.
First up is Brainy.
Smooth-operator Lex reminds him that its all part of the process of getting Gemma to trust him.

He mocks her idiotic ringlets and noxious porcelain cheekbones (way harsh, dude!
), but she assures him they lull the humans into a false sense of security.
That sounds… bad.
Speaking of the supers, they’re having trouble locating Leviathan.
But searching for any modern traces would require a visit to the special collections room.
Worse, Petes family ends up under surveillance, so he makes plans to go off the grid.
He also reminds Alex that she needs to adjust to not having the military at her back anymore.
Do it, do it!
It turns out to be Eve, whom Kelly recognizes right away.
Naturally William cant leave this alone, and as he follows Eve down a sketchy alley, hes black-bagged.
Tune in next week to see what happens to the tall, accented man!
Meanwhile, Dreamers dreaming.
At first she sees Brainy in the Leviathan headquarters, turning into his green alien self and laughing wildly.
By now, Nias at the end of her rope with Brainy.
And wheres Lex for all this drama?
as their violent survival instincts kick in.
When Lomelis attacked by the rioters, Lex wades in and get this!
actually engages in fisticuffs.
Who knew he had it in him?
Lena does a full Q-wave reset while Lex distracts everyone with portal watch antics.
Lenas not afraid, though, and coolly calls him a monster.
But that doesnt mean I have to be one too.
Although he lost the support of his sister, Lex is still in command of the situation.
By the end of the episode, Karas at a loss.
No Brainy, no DEO, no Lena to build her a kryptonite suit.
But not so fast!
A knock on her apartment door turns out to be Lena, and Kara wordlessly lets her in.
Kara listens in silence, then stonily invites Lena to sit down as we go to credits.
