The knife pass without a single glance is classic Skitter 'round 2, time to keep going'. Creepy as hell.
Skitter being shown to attack the S9 after they arrive is well done. She wasn't attacked, people she was trying to protect were, and she charged in anyway.
That she deflected the spinning knife attack twice and still got slammed with the kick, excellent.
You can see she's terrifying, you can get the feel she's outmatched, you could sense she can escape but that she's going in again anyway, as long as it takes.
