Loki had come home a little while earlier. Taking the shape of a cat, he'd slipped into the house unseen by anyone and had gone upstairs to the room he shared with Freya, somewhat subdued.
Freya couldn't find Loki, him being in cat form, so she went to her room. She noticed the cat and picked him up, "How'd you get in here, little fella?" She said to him, thinking it was just a stray cat. xD
"Not really. You're always complaining about me getting my own way; well, you won this round. I didn't want to do it, but I did anyway cuz I had to have revenge. I should remember that whenever I get revenge, it hurts me as well as the other person."
