Amazing Spider-Man #504

Tess Black, a New York stock trader, is actually Loki's half-human, half-Frost Giant daughter. The sorceress Morwen possesses her for her power.
After Loki and Spider-Man free Tess from Morwen, Loki uses his potent hypnotic powers to place Tess in a deep sleep, where she'll forget the experience and be able to live a normal life again.
