'Strike first, taunt later' was something that Loki had to remind himself of as well. He wasn't sure if he had picked up the bad habit from Thor or if he just liked to hear himself talk, but Loki knew that he occasionally had the habit of talking during a fight as well. Better to concentrate on the matter at hand.
Loki wasn't bothering with his knives here for once. Instead, he was simply going to attack her with magic. He did have one idea, more of a last minute thing, that he would only pull out if it was life or death, but it was comforting enough to at least know that he had it, even if he never wanted to use the ability.
He watched as Glorificus burst through her window when she realized that someone was out there, and couldn't help but be amused by the face that the creature made when Thor flew into the air, much less when he actually slammed the hammer into her and knocked her down to the ground.
As soon as she got back up and knocked back Thor, Loki launched in, throwing a blast of green energy at her and knocking her slightly back again. Yes, he doubted that, despite her quickness, she was expecting anyone around who was just as quick on their feet back.
