Something similar to an Einstein Rosen Bridge formed in New Mexico. Excitement and hope bloomed in the heart of a certain woman of science's heart as she read the reading of the storm that disappeared as soon as it came. She hoped that it was the one who had stolen her heart come to see her. Agents of S.H.I.E.L.D and the woman of science rushed to the suspected Bifrost site and what they saw there astonished them. A beautiful dark skinned girl no older than thirteen years of age lay on the ground before them. She was donned in what they suspected to be Asgardian armour, for her armour was inscribed with runes eerily similar to those inscribed on Thor's armour. A loose, silk navy blue dress that complimented her dark skin, a metal corset, high heeled silver boots and a red flowing cape. She was the epitome of beauty and elegance. After a few minutes hesitation the S.H.I.E.L.D agents and the woman off science gathered her up and carried her to their vehicle to their base where they would heal her to the best of their abilities.
