Function, IJ! Function!
There was a moment of weakness, as the earlier concusion caused a spell of dizziness. Katrina making a series of rapid blinks while gravity threatened to overwhelm her sense of balance - and spatial awareness. The biological equivelant of an aircraft cockpit running into a magnetic storm and losing control of its avionic instrumentation.
Enough, ultimately, for Elizaveta to succeed. Even as Katrina managed to get to feet, only to... Stumble in a very unlady-like, semi-balanced heap on the vehicle's side.
God, she felt older than Nixon... No, wait. She was older than Nixon.

Hell, what was the year?

She was dazed and made a vicious lunge, but ended up missing. Now was most definitely the time to get away from the thick of it, when neither could realistically claim victory.
Mainly, because it would probably come at the cost of at least one of their unlives.
