Newton “Newt” Scamander (b.1897) was a famous Magizoologist and author of Fantastic Beasts and Where to Find Them. He travelled to a hundred countries across five continents researching his book and observing many magical creatures.
Lady Sif journeys to Midgard in order to try to understand Thor’s fascination with Jane Foster. She didn’t expect to like her and her companions so much. Jane talks about bridges and stars and Darcy teaches Sif to drive a car. Sif tries to repay their kindness by teaching the two tiny Midgardians how to wield a sword, but it ends with Darcy threatening to taser everyone in sight. Sif is eventually called back to Asgard to assist with battle preparations. She leaves with the promise to visit to her new bffs. (Darcy taught her that; It means best friends forever.)
