Locked Away (30 Days) [Avengers]

Loki's invasion was thwarted thanks to the interference of Thor and the Avengers. Sending Thor to Earth, however, had used up too much of the All-Father's magic. It would take him a month to be capable of stabilizing the power of the Tesseract, and, until then, he would not allow it onto Æsir soil.
S.H.I.E.L.D., under pressure from Thor, arranged for Loki to be placed in comfortable confinement while they waited to be taken home. Loki, however, did not consider his confinement "comfortable." The agent S.H.I.E.L.D. had assigned to watch him was far too frustrating for Loki to ever call those 30 days comfortable. Where they revealing? Yes. Mind-altering? Yes. Life-impacting? Yes.
But comfortable?
Not for a moment.
