Loki got blinded with spell and needs to wait for effects of it to were off. In the meantime, he attempts to deal with his impairment with the help of magic and becomes the biggest nuisance of Avengers compounds. Since everyone has enough of ducking from randomly flying objects, and the constant presence of repair crew putting back walls that ended in Loki’s way, you got hired as a temporary assistant for Loki. You took this job because in your situation there would never be other better offer available, and the dreaded moment when Loki’s ire will turn on you. Loki turns out to be well-behaved, just riddled with fear over new situation mixed with boredom caused by lack of access to his usual pastimes. When he agrees to receive your help, he learns fast from your own experience with vision loss and is a great company to be around.
