Let's see... Russian, can fly a helicopter... I have an idea.
I start pouring ingredients into my evil cauldron as I make the evil concoction that will allow me to recover my Cookie undetected. Sodium chloride... fermented, aged solid milk of a heifer... wheat that's been ground and reformed into the shape of the crescent moon...
Finally, when it is finished, I take a long, big whiff of my creation. Delicious, tempting, and irresistible. Perfect to bribe this potential ally.
I find her crouched on a rooftop in Moscow, and when she sees me, she nearly shoots me with an electric discharge from one of her Widow's Bite gauntlets.
"Who are you, and what do you want from me?" Yelena asks, eyes narrowed.
I pull my concoction out of my bag. "I have something you want."
She still seems suspicious. "And what do you think I want?"
"I made macaroni, if you want some."
Immediately, her eyes light up, and I know she's interested. "All I need you to do is get me onto a helicopter headed for St. Petersburg. Then, the macaroni is yours."
She agrees, and a few minutes later, we're on our way. It's not long before we see your helicopter, flying lazily along, unaware of the second helicopter right behind it. I hand Yelena the macaroni, and she hands me a rope, and a firm nod.
"You'll need to be careful. If you get hit by one of those blades-"
"I know. But this has to be done." I stiffen my lip and stand up straight. "It has to be done, for the sake of the Cookie. If I don't make it back, please, tell my mother I love her."
Then, I leap from the helicopter, swinging down on the rope, and narrowly avoid the spinning blades atop yours. I land on top, rip open the door, and grab my Cookie from your hands, then jump, unfurling my parachute as I descend, cackling maniacally.
