Cap was almost straining herself to make the arm breaker as tight and straining as possible.  Only able to rely on Winter Soldier’s arm to keep herself from taking a long fall towards the concrete floor below.  That might have been a mistake on her part but it also ensured that the only thing Winter Soldier could do to stop that pain was basically fling them both over the railing.  Really he couldn’t be that desperate...

Suddenly feeling the guard rail slip out she realized that Winter Soldier was willingly letting himself go over the rail and towards the floor below.  In a sudden desperate move Cap let go of Winter Soldier’s arm.  Trying to grab hold with either hand the balcony flooring to keep from slamming onto the concrete from who knew how high up.  A flimsy grasp was all she could muster and it didn’t take long for it to slip from her grip.  Causing her to flail as all she could do was try and land straight on her back and not stiff.  

The two smashed to the ground with the thundering, hollow thud against the open air of the building.  Dust kicking up as they both laid motionless for a moment.  Cap herself didn’t feel dead, or indeed much of anything for a time.  Trying to move her arms and legs did yield results.  Though it also caused pain to course through her and wake her back up fully.  As she tried to get back to her feet, hissing from all the internal injuries she wasn’t looking forward to learning about.  The SHIELD operatives split up, one half finishing getting Ms. Haines out of the dangerous situation.  The others along with Black Widow approaching Winter Soldier cautiously to arrest him.  “Careful...”  Cap let out as a warning as Widow nodded to her, turning back and aiming a pistol out at Winter Soldier as a SHIELD agent began to pull out heavy duty handcuffs.
