I've moved her and she just teleports. She doesn't even stop floating.
She got grabbed by the Archon King, who was attacked by someone in overwatch. This disrupted the action, and this person was able to take an action (I executed the Archon King at basically full health because of her lol). She is still floating and teleporting (even when i was evacuating her).
Moral of the story: Get grabbed by the Archon King, you get to float and teleport.
