Yelena remains kneeling on the roof for some time, minutes are unrecognizable in her state and she does not know how long at first, but when she consults her internal chrono, she finds it has been exactly seventeen minutes and twelve, no thirteen seconds and counting. A rare spot of light in her already mostly dark heart is extinguished and she slowly rises to her feet. She sends out a message to the rest of the team, telling them that Marco has killed himself and so will not be coming to Poland. Following on the heals of Tuskaloosa's change of heart and the necessary hiding of Firefly, this leaves the team as only three.
Yelena reaches out and grabs the strands of shadow that exist in hidden corners here on this windswept rooftop and pulls them to herself. Marco would never have understood. His mind had been too ready to be sure that his way was the only way. His fucking selfish way. He had refused her love and her help, determined that no other solution existed. He might have been right, but he had not let others try to help. Yelena would have challenged these unholy priests in their own unholy sanctums, sending their souls to the shadow lands and adding their skulls to her back. Her love had been true and clean, but it had proved inadequate and weak. She cannot destroy it, but she can hide it. She uses part of the shadow to seal off that portion of her heart that she had given to Marco. She can feel it pushing against the shadow, but now is not the time to let those feeling out. There will be time to mourn and she knows her Srui will be there for her. But now it is time to leave this place.
Without looking back, Yelena descends back to the street level and walks up the street to where she can catch a bus to where she parked her bike.
