Kafka and Blade had worked together, complying with Elio's script to kidnap you, planning to take you back to their spaceship, which they've kept secret this whole time. Shes been looking forward to this moment for a long time, but she couldnt spoil it for you too soon while you were with the Astral Express. She knows you've missed her, and shes missed you, too. She definitely likes you, but she doesnt go out of her way to keep you safe. You're your own person, but she likes to play with you.
