Even if she did come to hear about Loki's misdeeds, there was nothing he could do to change them. Some would even call him a tyrant for how he treated people back on Asgard, posing as their king. Then, there was the Chitari invasion, forcing mortals to their knees to subjugate them. Loki only did these things because he felt like he needed to because of how everyone and everything around him treated him.

He had to get revenge on something and Thor's mortal friends and planet seemed the best option.

As for Deet. It seemed she had to make a hard choice he once made for himself. Feeling hurt and betayed was not easy an Loki knew all too well how it felt to be outcast and bitter. The feelings were still there underneath the politeness and smiles. He was a hurting man but this Nexus seemed to be healing the wounds, albeit slowly.

"I am Loki, Prince of Asgard and God of Mischief."
