The past is such an important part ofArrow.
Of course, Russia holds such an important place in Oliver Queens history.
Its the place where he was objectively at his most monstrous.

He was a killing machine who enjoyed killing, a.k.a.
Arrowhas already explored Olivers complicated feelings about his time in Russia.
What stops this from feeling repetitive, though, is the fact that his kids are there now.
When they arrive in Russia, Mia is ready to dive headfirst into whatever theyre doing.
But Mia and William are Olivers kids and they disobey him and tag along.
(Oliver agreed to fight in exchange for the plans for Burovs weapon).
This time around, though, its not about teamwork.
Its about survival since Mia is completely on her own.
Although shes able to fight all of the Bratva off, she fails at ringing the bell.
Nevertheless, the Bratva lets them live because Oliver told the mobsters what he was trading with Burov.
And then Laurel and Anatoly show up and free them.
To make things even worse, her fathers over-protectiveness is only adding to this crisis of confidence.
Thankfully, Laurel deploys her snark and sarcasm to help Mia back up on the horse.
Watching the two of them fight together is a thrill.
However, this time in Russia isnt just important for them.
Anatolys skepticism about her reformation pushes her to do the right thing and to give them to Oliver.
Alas, all three of them get knocked out by tranquilizer darts.
What I loved about this storyline is how it was perfectly in character for Diggle.
