Can anyone explain this?
Now before anyone goes for the obvious "it's his Q" answer, Kass clearly hits Kat with his q before she shunpos onto graves. You can see the "Silenced" timer above her. How would his Q disrupt the ult if it was used a full second prior to the ult. Also you can see the ult channeling, and yet she isn't ulting, moving, or doing anything. She doesn't appear to be stuck in the wall because Kass ults right where she was standing.
