In Arrow Season 2, Episode 6 "Keep Your Enemies Closer", Oliver Queen visits a Russian prison to bust someone out of it.
There, he says something presumably intimidating in Russian, and which makes the gulag guard hand over the keys.
Felicity asks Oliver what he said, but he simply responds with "Please" and a wink.
What was the actual approximate English translation of what Oliver said in this scene? (And what was the Russian, in Cyrillic if possible?)
